I kicked by Fairfight but I didnt cheat...

[Bonnuit_Monsieur]

 No idea what the hack is happened to my acc.

I can't join server but I can see this,

'Game disconnected: you were kicked by FairFight. Stated reason: 1 Week Suspension - LvL3 Monitoring Active #UYt8E5'

What's the problem? I never used cheat program in this game.

Bloody Fairfight...

Fairfight can suspend you for other things than using cheat programs. Exploiting, statspadding etc. is also not allowed.

As for your 1 week ban, you will just have to wait it out.
