How can you think its okay to permanently ban a loyal user based on nothing but your own judgement?
Isn't it his site?
Don't you think he should be able to ban whoever the hell he wants for whatever reason he wants?
The internet is big, go find help or lose your money somewhere that wants your action.
Don't be so ignorant.
There are certain legislative laws that oppose the action of banning users without a valid reason that are in place specifically due to casinos banning players who win
There are also laws making it illegal for him
not to ban you if you do or say something that makes him think you have a gambling problem.
But this is the internet, and he told you that you aren't welcome to play on his site, so move on.
If you're really delusional enough to think you have some legal right to risk your money against his money then call a lawyer and good luck.
