I always wonder what gives them the right to keep your coins. What happens to those if they are not returned to you?
I suspect their terms and conditions allows them to hold the coins. I wonder if this practice would hold water through the justice system though. Not that I intend to pursue anything legally, but if someone had some serious coins locked there...
Obviously their terms and conditions allow them to hold the coins at will because what warrants them holding your coins is based on their view of what is suspicious activity and this could literally be anything at all.
