Russia has been not been a permitted region since 2018. This is in our terms of service, and had he attempted to place bets without hiding his location, he would not have been permitted. If he snuck by our KYC team in 2019, it does not mean that play from within Russia was permitted then and certainly does not mean that it is permitted now. His account was not on our radar until recently, because he had a nearly 3 year gap without play until he returned on 23 Nov.

We do not refund previously lost deposits, which is standard procedure among all operators, and the recommended action of all mediators. The reason for this is if losses were returned, any player who lost could just come back and break a rule to get their losses back. Additionally, the player was up over 3 BTC from his play in 2019, so he should consider himself fortunate to have received anything back, as we had no obligation to do so.
