As any of your know who have had a Sportsbook account, they have their promo props every day.
"Wager on who will get to 10 points first, if the first point it scored by Dirk Nowitzki or Dwayne Wade, winning wagers will be tripled". Well I thought I would be slick and bet both sides. When I won, I got an email saying I "abused the promotion" and the promo would no longer be offered to me. Two days later my account was closed. They told me they would wait until my pending wagers had been graded and then send me my balance. They canceled a future I had on Paul Casey to win any major at 100-1 (this week it was down to 15-1). They wouldn't give me any reason as to why my account was closed although it's pretty easy to guess.
So just a warning, if you are any kind of winner, even a small one (I am a 50-100 dollar bettor per game) and you try and use your brain to out-wit the SPED bookmakers they have working at that place, you will likely be done.
I will say my money was refunded in full to my CC within 5 days though. No complaints there.
