A lot of you have probably seen the Today/Tonight special on bookies banning and limiting the accounts of successful punters. They track your betting habits and if you show certain betting patterns you're done for, even if they are way up on you. I trade and lost tonnes of money through both Sportsbet and Ladbrokes - they were fine taking the money ofcourse, but as soon as I had a win with both Ladbrokes and Sportsbet limited me immediately. I am relatively new to this, but have the feeling it's because they're both UK owned; is this correct? If so, is this standard practise for UK bookies?

Anyway, my question is do the TAB ban and/or limit successful punters the same way these other jokers do?
