He's playing right now.

I played with him today. Not sure it's enough for a permaban, but he's annoying to say the least.
He spams very often. Every time he accepts a knife fight, he runs away until time runs out and both players die. If there's a map he doesn't like, he tries to camp somewhere so people get tired of waiting and rtv. On another map I saw him stay in spawn and buy smokes and flashes and spam them.
Regulars tell me he's usually like this.

I didn't take a demo so it doesn't really matter, but I'm sure he'll do it again. He's just exemplary of the current crowd that plays on that server (well, at least a part of it).
