I can also assume that Malwarebytes may well have complained to theymos about selling their license keys on our forum. Selling their license keys is prohibited by the Malwarebytes Software License Agreement. Therefore, it's quite possible that theymos itself banned those who were selling keys and deleted their threads 
Does this mean that everyone who sells licenses for various AV and other software should also be permanently banned (and there are dozens of them), or maybe the forum will allow them to continue selling until one of those companies officially complains to the forum? I think that the rules for Digital goods might need updates to prevent future misunderstandings (perma-bans).
My guess is the
✅ ID (FRONT + BACK) PROVIDED
✅ PROOF OF RECIDENCE PROVIDED
is the bigger problem.
