What am I missing here? I admit it's late in the day and me eyes is tired, but 1) I don't see a threat and 2) I don't see negative feedback by Lutpin on OP.
I had no idea betcoin was in trouble either, but I'm not in their sig campaign and I've never used their service and I don't even follow crypto news much. If they're proven, or even highly suspected to be scamming then I'd say people should be given warning to remove the signature if that's the issue. Some of the campaigners might be ignorant of the facts and not intentionally promoting a scam. I was ready to ditch Yobit in a NY minute if I got wind of a credible scam accusation. Either way, this needs to be worked out with Lutpin. All you're going to get here are zillions of opinions, not all of which are going to help you.
Edit: Wendigo, I realize you're frustrated but I wouldn't just quit. Stuff can be resolved, and Lutpin is from what I've observed, fair and level-headed.
