Scam or not, we paid via the pool fee for his services, which conveniently forgot to pay about 15% of the total amount I've mined there.
If the 15% that I'm missing is representative of what others have lost, the pool is conveniently disappearing about $9,500/month in XMR.
That XMR isn't just disappearing into thin air. If I were losing $9500/month I sure as hell would not be doing ANYTHING except stopping the loss.
Just a little bit too convenient of a bug. Maybe it arose as a legitimate bug, but, not responding to reports for months, and ignoring any customer's inquiry is absolutely intentional. If he were being "above board" he would inform people there is currently a payout bug that he will resolve when he gets time.
Imagine if an ATM at a bank consistently "malfunctioned" and only dispensed 85% of the money it deducted from your account? Once is an oops, twice is suspicious. Going on for months on end after being reported multiple times? Damn right that's intentional.
