Thunderf00t (real name Phil Mason) is a blogger who was a member of FreethoughtBlogs in June and July 2012.
He has had a long history of YouTube, being notable for his series "Why Do People Laugh At Creationists?" and his feuds with VenomFangX and others.
After an introductory post, he contributed to the Misogyny Wars by arguing rather vehemently that conventions do not need harassment policies. His main argument was that he once playfully bit a woman's leg, an act that she seemed to enjoy.
He was soon banned from FTB, but the drama did not stop there. He revealed that he peeked in some private e-mails in FTB's admin mailing list (Thunderf00t/Phil Mason, treacherous hack » Pharyngula).
