What happened::

50BTC.com (member) ran 50BTC.com mining pool.  On about October 18 2013 the pool stopped payouts of mining earnings.  Suspiciously, this was right after an announcement that they would be switching to DGM reward method from PPS.  50BTC.com (member) has not been on the forum since October 28, 2013. 50BTC.com claims pool was conveniently hacked and all mining earnings were lost.  Lack of communication and avoiding questions from pool members makes the situation appear very fishy.
