Common practice is to freeze account and user wouldn't be able to login, I doubt he will be able to get back his recent deposits. Just expensive lesson to learn and next time user will not blindly deposit before checking terms conditions.
As stated support, the deposit is always refunded unless winnings are canceled due to violation of the rules and the deposit is lost while betting:
In case of an account being closed - our security checks it and, depending on the results, restores or refunds it - in both scenario funds are being returned to a player. It is written in our ToS and seen here on the forum.
Sincerely,
1xBit team
Let's wait for what support responds in this case.
