There's an anti-tk mod on server, so i dont know if the previous kills was on purpose or accident. As for killing you and leaving, ehh its happens. For admin disrespect from previous bans and disrespecting you, id say 1-2 month ban should do the trick. Hopefully he will learn his leson, (most likely he wont), and comes back, when he disrespect you any admins, then perma ban. IMHO. Lets hear what ULA and CLAN has to say.
