Just out curiosity. When people are making withdrawals and him processing them but sending them back to their accounts, would he back taking the fees associated with it. His fees were greedy at 0.001 when everyone else was 0.0001, it would explain a fair bit. For every 1000 transactions he gets a free btc and gets to skim a few times then send what ever is left over or the multiple small transactions.

Plausible? Just a wild thought.
