Yes, I also received it, 2 times.
As far a I remember they're sending email with header "Your account has been refunded" and indeed it was a moneyback for cash game.
Not sure about the bots, they refunded me for a person I had chat with, and I could leave that table having +25, but ended up having -20.
I guess that they're refunding for
gambling vs moneylaundrung accounts. Hackers can use
poker sites for washing stolen credit cards or bank accounts, and since you can withdraw to Bitcoin at ACR, then I guess these hacksters are trying to work at this platform.
Well it's great to know that they're keeping their site clean and refund victims, I had my account blocked for several days at
888 during investigation for same reasons several years ago, and 888 refunded nothing. But it was about HU SNG for $50 there, and I won 2 out of 3 games against suspicious player...
