@OP, maybe try to be more transparent here. Personally, I don't like the words "PM" when it comes to opportunities, as it mostly disappoints me.
he most likely invites links to people via PM, that's why he tried to make it even more interesting.
and maybe he has something special for the user who has been banned on Bookmarker which I think that very risky to get a fool or scam if already deposit and registered by the link he gives.
In my understaing, OP is not trying to get referrals here, but he has been limited by almost all the casinos and sportsbooks and he is trying to find a way he can bet again, and that is the reason why he said that he has an offer one cannot refuse, which means he will probably pay money or something in return for making bets for him.
Whoever tries to get into his words and does what he says will only pose threats to themselves and their accounts at a casino or sportsbook used. He probably has done something suspicious that caused him to get limited in every casino out there.
