MEMORANDUM OPINION
Before the court is defendant Craigslist, Inc.’s motion for judgment on the pleadings. We grant the motion for the reasons explained below.
BACKGROUND & PROCEDURAL HISTORY
In this diversity action Plaintiff Thomas Dart, the Sheriff of Cook County, Illinois, alleges that the “erotic” (now “adult”) services section of Craigslist’s popular Internet classifieds service facilitates prostitution and constitutes a public nuisance. (Compl. ¶ 1; id. at ¶ 5 (alleging that the parties are diverse and that the amount in controversy exceeds $75,000).) Craigslist’s users create and post “over thirty million new classified advertisements each month” for, among other things, “jobs, housing, dating, used items, and community information.” (Id. at ¶¶ 11, 14.) Craigslist’s website, which displays the ads, is viewed over nine billion times each month. (Id. at ¶ 15.) The webpage located at “chicago.craigslist.org,” one of many region-specific webpages on Craigslist’s website, displays Chicago-related listings arranged by categories (e.g., “for sale” and “services”) and subcategories (e.g., “antiques” and “computer”). (Id. at ¶¶ 11, 25; see also id. *962 at Ex. A (screenshot of the webpage at “chicago.craigslist.org”).) Craigslist created the categories, but its users create the content of the ads and select which categories their ads will appear in. (Id. at ¶ 11, Exs. A & B; see also Def.’s Mem. at 2.) Users posting ads on the website agree to abide by Craigslist’s “Terms of Use,” which prohibit posting unlawful content. (Compl. at Ex. A (screenshot of “chicago.craigslist.org” with a link to Craigslist’s Terms of Use); Answer ¶ 18.) 1 Users browsing the “erotic” subcategory — which is (or was) the website’s most popular destination — receive an additional “warning & disclaimer” stating that users entering that section agree to “flag ‘prohibited’ ” any content that violates Craigslist’s Terms of Use including “offers for or the solicitation of prostitution.” (Id. at ¶ 35, Ex. C.) Below the warning is a general “erotic services” link, and links to further subeategories (e.g., “w4m” (women for men)). (Id. at Ex. C.) Craigslist also gives users the option to search through ads using a word-search function. (Id. at ¶ 26.)
Sheriff Dart alleges that, notwithstanding Craigslist’s warnings, users routinely post advertisements in the erotic-services category “openly promising] sex for money.” (Id. at ¶ 17.) Based on the samples that he cites in his complaint most of the ads are veiled (sometimes very thinly) using code words. He alleges, for example, that “roses” mean dollars and “greek” refers to anal sex. (Id. at ¶ 30.) One advertisement states: “15 Min $50 Roses ... 1 hour $150 Roses” — so much for the code— and “How About A G-R-E-E-K Lesson I’m A Great Student!!” (Id. at ¶ 32.) 2 Other sample advertisements are more ambiguous. (Pl.’s Resp. at Ex. 2 (“HELLO GENTELMEN NOW YOU MEET JADE AND TIPHANY WE DO TWO GIRL SHOWS AND INDIVISUAL CALLS!! WE GARAUNTEE THE TIME OF YOUR LIFE!!!”) (spelling errors in the original).) Many of the ads include nude or nearly-nude pictures, ostensibly of the person posting the ad or offering his or her services. (Compl. ¶ 29; see generally id. at Ex. E.) Sheriff Dart cites the advocacy group “The Polaris Project” for the proposition that “Craigslist is now the single largest source for prostitution, including child exploitation, in the country.” (Id. at ¶ 38; see also id. at ¶¶ 41-45.) Law enforcement officials (including plaintiff) regularly conduct prostitution stings using information culled from advertisements in Craigslist’s erotic-services category. (See, e.g., id. at ¶ 57.) 3 By his own count plaintiff has arrested *963 over 200 people through Craigslist since January of 2007. (Id. at ¶ 58.) Some of those arrested were charged with pimping minors. (Id. at ¶¶ 59-62.) He estimates that between January and November 2008 his department devoted 3,120 man-hours and approximately $105,081.00 to make 156 arrests. (Id. at ¶ 78.)
Count I of Sheriff Dart’s complaint alleges that Craigslist’s erotic-services category constitutes a public nuisance. See Restatement (Second) of Torts § 821B(1) (“A public nuisance is an unreasonable interference with a right common to the general public.”). As “evidence” of the public nuisance he alleges that Craigslist violates federal, state, and local prostitution laws. (Id. at ¶ 93.) He contends that Craigslist “solicits for a prostitute” within the meaning of 720 ILCS 5/11-15 by “arrang[ing]” meetings of persons for purposes of prostitution and “direct[ing]” persons to places of prostitution. He also alleges more generally that Craigslist makes it easier for prostitutes, pimps, and patrons to conduct business. (Compl. ¶ 134) (Craigslist “streamlines the prostitution process”); see Chicago Municipal Code § 8-8-020 (“[N]o person knowingly shall direct, take, transport, or offer to direct, take, or transport, any person for immoral purposes to any other person, or assist any person by any means to seek or to find any prostitute.”) (emphasis added); see also 18 U.S.C. § 1952(a)(3) (making it unlawful to use any facility in interstate commerce with the intent to “promote” or “facilitate the promotion of ... any unlawful activity,” including “prostitution offenses in violation of the laws of the State in which they are committed.”). He seeks to recoup the money his department has spent policing Craigslist-related prostitution, compensatory damages, and punitive damages. (Compl. at 26.) In Count II of his complaint he requests an injunction requiring Craigslist to desist “engaging in the conduct complained of herein.” (Id. at 27.) After Sheriff Dart filed this lawsuit Craiglist voluntarily changed certain aspects of its service. It terminated its “erotic” category and established a new “adult” category, which is subject to a “manual review process.” (Def.’s Reply at 3.) It also reduced the number of subcategories from 21 to 5. (Pl.’s Resp. at 1 fn. 1.) Sheriff Dart contends that these changes are only cosmetic and that users continue to post unlawful content in the “new” adult-services section. (Pl.’s Resp. at 1-2.) In a footnote in its reply brief Craigslist purports to reserve the right to pursue dismissal on mootness grounds, but it does not press the argument or describe its new policy in any detail. (Def.’s Reply at 4 n. 1.) Based upon the parties’ submissions we are persuaded that there is still a live controversy. 4
DISCUSSION
A. Legal Standard
We review a Rule 12(c) motion for judgment on the pleadings applying the same standard we apply to a motion to dismiss under Rule 12(b)(6).
See Buchanan-Moore v. County of Milwaukee,
B. Subject Matter Jurisdiction
Although neither party raises the issue, we must decide whether we have subject-matter jurisdiction before addressing the parties’ other contentions.
Wernsing v. Thompson,
C. The Communications Decency Act
Craigslist contends that it is immune from liability pursuant to Section 230(c) of the Communications Decency Act. That provision provides as follows:
(c) Protection for “good Samaritan” blocking and screening of offensive material
(1) Treatment of publisher or speaker
No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider.
(2) Civil liability
No provider or user of an interactive computer service shall be held liable on account of — (A) any action voluntarily taken in good faith to restrict access to or availability of material that the provider or user considers to be obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable, whether or not such material is constitutionally protected; or (B) any action taken to enable or make available to information content providers or others the technical means to restrict access to material described in paragraph (1).
47 U.S.C. § 230(c). Sheriff Dart does not dispute that Craigslist provides an “interactive computer service” within the statute’s meaning.
See id.
at § 230(f)(2);
see also Chicago Lawyers’,
Craigslist contends that § 230(c)(1) “broadly immunizes providers of interactive computer services from liability for the dissemination of third-party content.”
See, e.g., Zeran v. America Online, Inc.,
An interactive computer service “causes” postings only in the sense of providing a place where people can post. Causation in a statute such as § 3604(c) must refer to causing a particular statement to be made, or perhaps the discriminatory content of a statement. That’s the sense in which a non-publisher can cause a discriminatory ad, while one who causes the forbidden content may not be a publisher. Nothing in the service craigslist offers induces anyone to post any particular listing or express a preference for discrimination; for example, craigslist does not offer a lower price to people who include discriminatory statements in their postings. If craigslist “causes” the discriminatory notices, then so do phone companies and courier services (and, for that matter, the firms that make the computers and software that owners use to post their notices online), yet no one could think that Microsoft and Dell are liable for “causing” discriminatory advertisements.
Id. at 671-72. The plaintiff in Chicago Lawyers’ was free to use Craigslist’s service to identify and investigate the individuals responsible for posting discriminatory ads, “[b]ut given § 230(c)(1) it cannot sue the messenger just because the message *967 reveals a third party’s plan to engage in unlawful discrimination.” Id. at 672. 7
D. Applying § 230(c)(1) to Plaintiffs Public-Nuisance Claim
Sheriff Dart alleges that Craigslist itself violates criminal laws prohibiting prostitution and related offenses.
See Beretta,
Craigslist is like a newspaper, and unlike a phone company or computer manufacturer, in that it publishes information supplied by its users. Newspapers and magazines may be held liable for publishing ads that harm third parties.
See, e.g., Braun v. Soldier of Fortune,
Sheriff Dart insists, on the other hand, that Craigslist plays a more active role than an intermediary or a traditional publisher. He claims that Craigslist causes or induces its users to post unlawful ads — by having an “adult services” category with subsections like “w4m” and by permitting its users to search through the ads “based on their preferences.” (Pl.’s Resp. at 7; Compl. ¶¶ 86-87, 122, 134-36.) “A website operator can be both a service provider and a content provider: If it passively displays content that is created entirely by third parties, then it is only a service provider with respect to that content. But as to content that it creates itself, or is ‘responsible, in whole or in part’ for creating or developing, the website is also a content provider.”
Fair Housing Council of San Fernando Valley v. Roommates.com, LLC,
Sheriff Dart’s lengthy complaint relies heavily on a few conclusory allegations to support the contention that Craigslist induces users to post ads for illegal services. Even at this stage of the case we are not required to accept those allegations at face value, and they are not meaningfully different from the allegations that our Court of Appeals rejected just last year. The complaint’s remaining allegations plainly treat Craigslist as the publisher or speaker of information created by its users. Like the plaintiff in Chicago Lawyers, Sheriff Dart may continue to use Craiglist’s website to identify and pursue individuals who post allegedly unlawful content. Chicago Lawyers,
*970 CONCLUSION
Defendant’s motion for judgment on the pleadings (12) is granted.
Notes
. "By using the Service in any way, you are agreeing to comply with the [Terms of Use].... You agree not to post, email, or otherwise make available Content: a) that is unlawful, harmful, threatening, abusive, harassing, defamatory, libelous, invasive of another's privacy, or is harmful to minors in any way.” (Terms of Use, attached as Ex. 1 to Def.’s Answer, at ¶¶ 1 & 7(a).) "Content” includes "all postings, messages, text, files, images, photos, video, sounds, or other materials.” (Id. at ¶ 3.)
. Spelling variations, like the hyphens in "G-R-E-E-K,” are apparently used to avoid detection by automated screening programs. This subterfuge, and the use of sexual code words generally, is specifically prohibited by Craigslist’s "Erotic Services Posting Guidelines.” (See Answer at Ex. 5.)
. Perhaps reflecting the problem of ambiguous posts, Sheriff Dart alleges that in a typical sting an arrest is made only after the person identified in the ad offers an undercover officer sex for money. (Compl. ¶ 64);
see Chicago Lawyers’ Committee for Civil Rights Under Law, Inc. v. Craigslist, Inc.,
. One final procedural matter. On the date that Sheriff Dart filed his response to Craigslist’s Rule 12(c) motion he also sought leave to file an amended complaint adding two nonprofit organizations as plaintiffs. We denied his motion without prejudice. At the same time we granted a third non-profit organization, Coalition Against Trafficking in Women (“CATW”), leave to file an amicus brief. CATW’s brief paints a troubling picture of the illegal sex trade, but it does not shed any light on the legal questions before us.
. With a few exceptions Craigslist does not charge its users a fee to post ads on its website. (Compl. ¶ 13.) In late 2008, with the tacit blessing of 43 state attorneys general, Craigslist began charging users to post ads in the erotic-services section. (Compl. ¶¶ 45-51; see also Joint Statement, attached as Ex. 8 to Def.’s Answer (document executed by Craigslist’s CEO and 40 attorneys general, including Illinois's, announcing “new measures’’ to combat unlawful activity on Craigslist’s website).) Craigslist and the other signatories of the "Joint Statement” believed that the fee would curb unlawful ads and make it easier to locate the users who post them (users must pay the fee with a valid credit card). (Joint Statement at 1-2.) Sheriff Dart contends that these measures have not had their intended effect. (Compl. ¶¶ 52-53.)
. Sheriff Dart points out that the statute does not affect federal criminal law, but the reference in the complaint to 18 U.S.C. § 1952 does not bring his public-nuisance suit within that exception.
See
47 U.S.C. § 230(e)(1);
Doe v. Bates,
No. 5:05-CV-91-DF-CMC,
. Insofar as plaintiff implies that § 230(c)(1) applies only or primarily to defamation cases, (Pl.'s Resp. at 6-7, 8-9),
Chicago Lawyers’
squarely refutes that argument.

. Webster's Third New International Dictionary 120 (Philip G. Gove et al., eds., 1970) (arrange: "to effect usu. by consulting: come to an agreement or understand about: SETTLE”); id. at 640 (direct: "to show or point out the way for”).
. Each of the cases plaintiff cites is distinguishable on the same or similar grounds.
See Anthony v. Yahoo Inc.,
. We do not reach Craigslist's alternative argument that the requested injunction would violate the First Amendment.
