Twitter censors user for posting claim about Biden and bin Laden: A Twitter user was suspended by Twitter in a confusing incident. The user tweeted the following: "Several sources claim that it was JOE BIDEN that LEAKED SEAL TEAM SIX as being responsible for the killing of Osama Bin Laden. ASS.. Chinook shot down by RPG." His account was then locked and he was forced to remove the tweet. Twitter, however, claimed that the reason for this censorship was that the tweet violated "our Child Sexual Exploitation Policy."
