I have the same problem at this one:
http://orb.crypto-expert.com/
With this guy:
https://bitcointalk.org/index.php?action=profile;u=85405
When I'm the new guy, I tend to assume that any problem is probably my fault, but when the pool admin never responds to your messages, and the pool goes empty on a hot coin with no notifications, site banners or anything, the most reasonable conclusion left is that someone is intentionally ripping me off.
Is there anything that can be done about this, other than telling the whole cryptocoin world that the guy running the pool is a thief?
