Looks like they were on the bad fork of 365 coin
There was no fork, 365coin hasn't had fork issues. This went on for over a week and he kept assuring everyone that everything was okay. He told me on IRC that my coins were safe and I should keep mining. He dragged it on as long as possible to keep people mining and then wiped out their balances. This is a bad guy. There's bound to be pool ops who operate in bad faith. It's only bad news for the community if good people do nothing.
