The term anti stems from a Canadian TKer who goes by the alias /|r51-AnTi. It was originally called "AnTi-Teamwork" but because of his laziness (see also: Canadian), he shortened it to just AnTi.
After TKing on countless homelan servers, he was eventually range banned and couldn't so much as even play on them, much less TK. As a result of this, AnTi became seriously depressed and withdrew from society. In short, he became a very emotional hermit. As time went on, he realized more and more that his life had very little purpose when stripped of the ability to TK innocent players.
On Sept 28th, Anti took matters into his own hands. He decided, in a second, that a life without FF was a life not worth living. At approx. 5:40AM on Wednesday Morning, AnTi waited for one of his teammates to activate the elevator and proceeded to place himself under it, thus being crushed by it's return. He was pronounced dead at exactly 5:58AM Wednesday Morning.
