Hello, here the detection :

 [smac_eyetest.smx] player_id (ID: STEAM_0:1:XXXXX| IP: X.X.X.X) was banned for cheating with their eye angles. Eye Angles: 88 -517 0

It can be an error or no?

CS:S , FFA server without particular plugins

I highly doubt that it's any kind of false positive. I've never seen any legit player in CS:S with values remotely as high as -517. I've had multiple players banned in that range, and if you do a simple search on their name, you'll see multiple bans elsewhere (sometimes for Eye Angles as well) and for aimbot/etc, some even come with demos attached.
