Here's a new one.

On the forums this weekend, the player "Mentat" claims that he was a prop for a while and in fact received house funds to play poker with.  He also claims that he was refused a cashout for "around 30 coins" but that he received "nearly that amount over time to keep the games going".

So, it seems like Betcoin is paying their house players 30 coins, refusing cashouts, and not announcing that they employ (or the identity of) house players.  Sorry for no screenshots, I'm on the run and if nobody grabs them by the time I'm home I'll edit with them.
