I don't think this is a suitable solution since first all you need to provide fake documents for KYC or documents of other players from another country ( ... something illegal and really risky ).
secondly you are dealing "with money" they will not issue a warning but they will just seize your money in any case!!!
I don't think they spend time and money for legal action but there is also this risk.
This doesn't apply only to Playbetr.com but to any betting/gambling site that requires KYC and has a list of country blacklisted.
