_KiTA_ writes: Popular Wiki TVTropes recently underwent a purge after a troll complained to Google about content on the wiki. Any works that may possibly discuss risque content, including the recent hit animeAstarotte's Toy and Vladimir Nabokov's Lolita were part of the purge of works that had "pedophile overtones."
Most worryingly, the site made a special effort to prevent Google AdSense ads from being displayed on those particular pages, which means that Google is now claiming that even pages that do not have Google Ads directly on them are fair game for blocking your entire domain from advertisement hosting and Google Indexing.
Interestingly, this is not the first time Google has forced TVTropes (and others) to purge their website of unpalatable material, it is actually the latest in a in people using Google AdSense to harass websites they do not agree with, with an apparent focus on websites discussing Japanese media.
