Facebook purges video of preacher casting out demonic spirits in woman: TB Joshua is a well known Christian preacher and televangelist from Nigeria. After a U.K.-based organization filed a complaint to YouTube and got Joshua's channel shutdown because of videos that show him performing prayers to "cure" gay people, Facebook followed suit and removed a post from Joshua's channel as well, according to the BBC. The video Facebook removed reportedly showed a woman being slapped while Joshua claimed to be casting out a "demonic spirit." Joshua's Facebook Page has over 5.6 million followers.
