I don't think OP meant any harm by his mention of Russian gamblers, if they even are Russian, or that sportsbet is selectively targeting them. Not sure why some members are reacting so strongly to that.
Is it only me? I am seeing far too many newbie accounts are either getting scammed or playing forum politics.
My first thought was what adam0991 articulated:
I would assume it’s more due to the fact that all these topics are appearing on google, which is bringing new users to the forum to also submit their complaints.
My gut feeling is telling me this isn't a case of a bunch of alt accounts ganging up on a casino, though I certainly could be wrong. And since there have been a couple other threads from users reporting problems with sportsbet, I bet the newbies were probably directed here via a web search. Hell, that's how I discovered the forum.
