Craigslist, by shutting off its “adult services” section and slapping a “censored” label in its place, may be engaging in a high-stakes stunt to influence public opinion, some analysts say.

Since blocking access to the ads as the Labor Day weekend began — and suspending a revenue stream that could bring in an estimated $44 million this year — Craigslist has refused to discuss its motivations. But using the word “censored” suggests that the increasingly combative company is trying to draw attention to its fight with state attorneys general over sex ads and to issues of free speech on the Internet.

The law has been on Craigslist’s side. The federal Communications Decency Act protects Web sites against liability for what their users post on the sites. And last year, the efforts of attorneys general were stymied when a federal judge blocked South Carolina’s attorney general from prosecuting Craigslist executives for listings that resulted in prostitution arrests.

“It certainly appears to be a statement about how they feel about being judged in the court of public opinion,” said Thomas R. Burke, a First Amendment lawyer at Davis Wright Tremaine who specializes in Internet law and does not work for Craigslist. “It’s certainly the law that they’re not liable for it, but it’s another matter if the attorneys general are saying change your ways.”
