Kigen's Anti-Cheat

Thanks. I was playing on 3 maps there. de_dust2 and de_kabul2 was normal and after 10 minutes(so after playing over 1 hour on this server) playing on de_aztec I was banned.
My friend checked this command and Counter Strike Source after trying to change this value send msg that client can't change ...

I was banned by KAC http://infamous-clan.eu/bans/index.php? ... 076&Submit
STEAM ID to check (STEAM_0:1:13066076)
Banned by KAC or by Admin? Thanks in advance. PaNiCz
