Plaz has always been a nutcase. His entire presence on the forums and in the game was centered around trolling, narcissism, and attention-seeking behavior. This is evident if you go through his old accounts and notice how many of them end with a long, drawn-out forum Self Delete note about how he 'tricked us' by pretending to be someone else. Back on the forums circa 2012 we would always joke about how some new alt was actually Plaz because he had such a long history of coming on with a new persona, behaving like a psycho, and then being banned shortly after 'revealing his true form'.
To a more attentive and sensitive community, people might have flagged this as psychopathic behavior, but it was honestly just par for the course on the BLF. The difference between a guy who trolls because he's bored and trolls because he's a future honor student is not always so clear on a website like this.
I know I argue with you guys a lot about politics and such, but I'm still aware that you're all human beings who make rational choices and don't go about life with the intention to hurt other people (except for beachbum when he's being a cunt). What we've seen here today is a very visceral example of what happens when a person's sadistic, narcissistic delusions reach their breaking point.
