I was there too and was about to make a ban poll of the teamkiller (he also killed a clanmate of me, Toonarmy), but they told me an admin had banned him. Later on we heard that it was the wrong dude that got banned. I actually wondered why his name didn't disappear from the ban poll selection but thought it just hadn't updated.
I dunno if it was the same who attacked you, but if you see who teamkilled toon then that guy also teamattacked me and some others.
