As of about 6AM Central time: I saw at least one spinbotter, and a few other users threatening to use hax just to "make it even". Plus there was at least one TA/TKer.
Team Attackers/Killers:
:D!!!
Hackers:
.Dee Pee.# (mentioned having hax ready to go, and I believe also posted a URL to a hax site)
٠ђ®ύ٠ Appz (spinbot)
anti_chaeters (or something like that [or it could have said "f**k", full word though, instead of "anti", but that's how he spelled "cheaters"; Threatened to use hax to "make it even")
Suspected:
٠ђ®ύ٠ Quicksilver (I think that's his name; didn't spec because he left, then came back later after I disconnected, but he had a really high score when I checked through Xfire a little while after)
I think there were a few others (hackers and TA/TKers) but I don't remember the names
