I think that if the OP write about it now - it was fixed. Of course it is possible that the OP lies, or uses some casino feature thinks that it is bug.
Anyway, if he tells us truth i can only applaud him - $8.500 per month are really good money. But the same time i`m sure that it is impossible to repeat it now, so i don`t cares about it.
There’s no way to verify this but one thing is for sure if this is true that he earns profit in bulk not in monthly basis since exploit on casino can be easily found it by the casino owner even back then since they can track who’s player consistently draining their funds.
If OP is really a successful hacker that abusing exploit then it’s possibly that he do this one time big time on different casino that offers same game with same security exploit because casino back then are just the same dice site.
There may be some truth in what you say because, of course, when you are a hacker, it is very easy for them to exploit because they are hackers and they are able to eat their prey whole without any resistance.
And this is really the main purpose of a hacker, and that is just to exploit. That's it; there are no other reasons. That's why they are also pitiful, because everything these hackers do will also suffer in the end, for sure.
