It was the final straw after being repeatedly told to stop. Your first batch of posts was nothing but generally unreadable incoherent bullshit. You were asked to stop, and you didn't. If you don't like it, fuck off.
But the ban apparently helped. I mean, you racked up three warning posts almost immediately, and I sent you a polite PM about the forum rules. You didn't give a shit, so you got a temp ban. Now you're back and you learned your lesson, apparently.
You think I'm a knob for letting you disregard the forum rules completely? Again, if you don't like it, fuck off.
I've sent him the rules explicitly in a PM, too. He was warned several times, and all he did was "put his favourite comments about him" in his profile header. You come to troll, you get banned. No surprises.
