Sorry but I am going to have to mark this as invalid as I do not see enough evidence to hold a ban. Thanks for the report though!

Reasons of invalidity (Question form directed at Gamma):

• What rank did you agree on?
• How long after was the screenshot taken proving you were scammed?
• Were the diamonds ever sold to him? If not, it is technically not a all out scam considering you both lost nothing.
• Even though he admitted in a way, I still need hard evidence.

Thanks again Madi and if it comes up again, try to get Gamma to collect more evidence so further punishments can be held. I will also talk to the alleged offender in-game to insure he does not try to scam a player (Again or in general). Cheers! Locking and Archiving.
