Although some have gained Internet notoriety for their antagonistic, bullheaded, audaciously asinine, and all-around attention seeking tweets, no group is better at trolling than celebrities. This list takes a look at the most infamous trolls of Twitter. For some, trolling only serves as a boost to their star power. Others, it's done nothing but soil their names, and, in some cases, their checking accounts. No matter where they fall, though, one thing is certain: they be trolling. Oh, and before you even think to ask, the reason why Chris Brown is not on this list is simple: He trolls himself, which technically doesn't count. Better luck next list, Christopher.
