@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.
What is certain is that if there is someone who wants to work with Op it will only make trouble for himself because Op has been limited to every Sportbook which indicates suspicious activity.
Maybe he will offer something that is very profitable but the risk to his gambling account is also high when one day it can be banned by any Sportbook.
I'm not really sure if Op really does bad things on every bet in the Sportbook but for sure this is definitely something suspicious and not something to do.
