Did they just restrict you because you were making profit, how

don't mind the OP. Sometimes people just come up with ideas that's not even well refined and they think that they can easily lure people into believing there statement. What's now special about him that he gets kicked out of betting with the said betting platform while others aren't?
Or you were trying to cheat on them or something...
that's most likely the case and it's possible dude is just trying to recruit more of his kind to join him in this plan or maybe extort them in the process.
However, it will be difficult to believe what a newbie says here with how many post?

.
if what OP was saying was factual and beneficial, it wouldn't really matter that much if he had been on the forum for so long or if he had made a certain number of post on the forum. It's possible you can have a betting strategy that has been working for you in the past even without having any knowledge about the forum in the first place.
