As explained in the Shoutbox, the new update today has been breaking Sourcemod and a bunch of extensions, which in turned affected some plugins including our anticheat SMAC.
SMAC has been detecting the new taunts as aimbots (the eye angles violations) and has auto banned everybody using them tonight. It's obviously an error, and I've removed all the players (including you) that were wrongfully banned.
You should all be able to join our servers once again. Please let me know if you still can't.

If SMAC auto-bans again due to using one of the new taunt, please post here and I'll look into it.
Sorry about that guys!
(I knew the new taunts were going to be a pain. I foresee new exploits, hacks and issues thanks to these new taunts. Thank you Valve!)
