Yeah np TaaaDaaa.
I get the feeling there are many misconceptions as to why players get bonus banned at Rival casinos. I can't speak for all, but at least for ours, there's only 2 reasons: multiple accounts, or advantage play. That is, claiming promos on every deposit and continuously cashing out every time you just barely meet wagering thus causing a potentially dangerous situation for the casino.
If both of these things in conjunction are found (ie mult accounts and on one of the accnts, bonus abuse) the account will often be banned. Rarely will an account be banned due to just one of them as either one, alone, could be simply a mistake and not intentional.
Cashing out a big win, claiming comp points etc are all very much encouraged! We want our players to be happy and no one wants to play at a casino where they can't win and cash out! Players who win are always great publicity and wonderful word of mouth advertising!
Like I said, it's just when you claim a promotion on every deposit AND continuously cash out when just barely grinding out the wagering requirements. This is seen by the security as advantage play.
