I had always thought that it's the odds provider that limits the player, not the website. Maybe I'm wrong. Either way, I think sites would be better off removing minor leagues from available bets and save themselves from these threads.
I can easily get an account limited within 1 or 2 bets on Nfl or Nba main handicap line or over under. They don't care even if biggest market in the world, if you bet on a early line and you manage to beat the closing odds you're out.
