"They put ... invisible iFrame(s) in their Web sites to refer people to the complaint URLs, which caused huge numbers of visitors to report gay and lesbian items as inappropriate without their knowledge," he writes.

The inappropriate content reporting feature no longer appears to be present on Amazon.com book pages. "Weev" claims the option was removed from the site on Sunday, following his attack.

"Weev," incidentally, was profiled in a 2008 story about online "trolling" . The story discusses his reported connections to various attacks on LiveJournal as well as on cell phones and credit ratings.

Amazon's Stance

Amazon has yet to discuss exactly what led to the gay- and lesbian-themed book sales rank removals. Spokespeople from the company have gone on the record and promising it would be repaired. The Gay & Lesbian Alliance Against Defamation (GLAAD) has also indicated that it "reached out" to Amazon and received the same message.
