Not that this will necessarily help you but even though Betcoin has it's own cash game pool it is still connected to WPN for a majority of the tournaments.

Since Betcoin is connected if they are pulling a lot of shady activities you would think the rest of the network wouldn't want to associate themselves with this skin so have you tried contacting them such as the CEO who posts up on 2+2 reguarly?

He comes across being arrogant at times but when it comes to something this like this maybe he would take these accusations seriously where if anything they can put pressure on Betcoin to do right or rid themselves from this skin which is probably the source of a lot of these DDOS attackers since the hardcore bitcoin geeks flock to that site the most and some are big into doing that type of activity.
