I think good arbitrators aren't just about people who bust scams. That's to me very different. You need a few things.

Someone who is trusted to act on the right side, and who has shown in many instances that they can be trusted
Also well known in the gambling section, who also gambles, and has long experience there (this is super important to me)
Also knows the sports involved, this is about football matchfixing
Also has history of helping forum without payment or recognition

I don't disagree about holydarkness or anyone else mentioned, but I mentioned the ones I said because they fit all the above criteria, they actually gamble, they know the different sportsbooks, and I believe more important, they have been involved in arbitration before. At least I know two of them personally arbitrated, one even for me many years ago. They didn't take payment, and didn't even ask for acknowledgment, and even I know two of them helped sooo many people but you don't even see trust rating for that.

One more thing to respect objectivity and transparency Both Fairlay and the accused user should agree on this 'panel' also, and communication should be out in open, not in PMs. Just my 2 cents!
