Kigen's Anti-Cheat

Hello KAC staff

Im not so happy for my ban??
Me and my IRL friend did play some FFA on hes server, we had SV_cheats 1 on the server and we ridden something in the console so we could se each other (mat_wireframe)

but so i got banned for cheating infraction and why can my friend not unban me from hes server again??
i really confused?

can you help my friend to unban me again

my friend says that maybe its my skins on my guns?
