Classified ad site Craigslist has closed its “Adult Services” section, after a campaign by 17 states to have it removed. Attorneys general from Montana to Virginia wrote a letter to Craigslist chief executive Jim Buckmaster last month, urging him to shut down the erotic ads section. The link has now been blacked out and replaced with the word “censored”. The decision only affects the US version of the site. Craigslist has previously cited in its defence the federal Communications Decency Act, which protects websites from liability for content posted by users. The company has not yet commented on the recent removal.
