Plaz is talented at building and scripting. He was involved with a script that generated fake authentication keys, Badspot revoked his key. Plaz bought 2 more keys, threatened to put them up for resale, Badspot revoked them. There is a lot of history before any of this, however.
Plaz makes alternate accounts and trolls the forums intending to prove his point that this forum needs some form of security.
Quite. He's a nice boy, but, as I've stated so many times before, his pride got the better of him. He's fairly arrogant, and fails to notice that he is the one of the only people that are trying to be kept out, even though he constantly insists on higher security.
Kind of like Bush! Plaz also has a history of lying and manipulating. He wants tried to destroy iEvent, as well as BiT, and some how he went from one year being a 13 year old, to about a year later going off to Harvard Law School. He's a bright boy, but come on. >.>
tl;dr: Plaz is an arrogant boy with a lying problem, though he seems to mean well, he has been kind, an he is and intelligent boy.
