Good luck with cross-border enforcement.
Also the operator is completely legal/compliant with it's jurisdictions laws as they allow us players (many now blacklist the us, but some not )
So they won't accept any foreign judgement . That's why most countries rather target their infrastructure (psps/banking etc ..)
Even Eu countries had/have severe problems with Malta (due e.g Article 56A of the malta gaming act, which shields the operator from foreign judgements)
