The one good loophole these days that a few people i know use who have had restrictions with bookies online, is to bet on 888 or pokerstars because they're primarily poker sites but just offer sports betting, or 32 red which is a casino but just offers sports betting, these guys don't really give a **** how much you bet or if you win/lose because they're not solely based on sports betting gains etc.
Not my experience mate. I’ve never been able to get more than £20 on with Pokerstars
