This is a case of one high-profile Chinese developer who charges a casino for exploiting his gambling addiction and lack of English proficiency, which resulted in a massive accumulation at baccarat tables.
If I may get correctly every gambling site or casino do have language translator that translated English to many Languages on their site which they can read and understand how it's, except it was in other cases.
They already have ToS which is governing their overall gambling rules and whatever that isn't in correlation to their ToS would never be allowed.
