Then don't. If you promote them then you'll knowingly work with known cheaters and will send a message to all thieves that it's OK to fuck honest webmasters out of payment, as long as they come back and apologize for it. Not to mention that they'll most likely do it again and fuck you over as well. Once a thief, always a thief. Be sensible about this one, rip their heads off and shit down their necks!
