If they can identify cheaters, they should simply perma ban them. No ****ing about, just ban them, destroy and delete the account.
Allowing them to play in their own little world sends totally the wrong message (yet again) and that is that either they don't give a damn about them cheating, or they find it a laughing matter, with tolerance and resources going to give them their own corner to play in.
*******s. Hate them.
I've seen many a decent game totally ruined by cheating ,and a zero tolerance attitude towards it would be ideal, and the only thing I will ever applaud when it comes to cheats.
Sadly in this day and age, it will never happen.
