Jamz, what about create rules for these types of players, trying to set rules for levels of offenses such as:
Level 1. Cheater (captured using cheat) : banned 3 months (could still be accepted into a clan if the player shows something of shame)
Level 2. Cheat Recurrent (level 1 + caught using cheat again) : banned 4 months (cant be accepted into a clan, if this player enter a clan, the clan leader should be banned too)
Level 3. Cheat Recurrent Cheeky (level 1 + 2 + caught using cheat again)
for this level there is nothing to do. Dont cry, banned from masterserver for life.
