Not sure, but I don't think the SBR ratings have nothing to do with bookies limiting players. They are graded on different basis. I agree that limiting winners is highly annoying and I'd like to see reviews from this point of view as well. I try to steer away from bookies that are doing this, but it is hard to say before you win something. They don't really advertise it
Here is my stay away because of limiting list (aca where have been limited), if it helps somebody.
-BetAndWin
-Nordicbet
-Eurotip
-Interwetten
-Scandic bookmakers
-SportingBet
-24HBet, aca 24HPoker
-I am thinking that also Fonbet is headed that direction
If you want to bet more exotic euro sports I recommend Centrebet, Unibet and Expekt
