Bingoroom.com, Bingoroomnetwork.com, Brnnet.com Forced me to gamble away my winnings, Internet

Bingoroom.com is a major ripoff.  They give you a "bonus" on your deposits but the bonus comes with a high price.  They do have their policy listed on their site but I didn't understand it until I won 2 bingos and tried to cash out.  In order to cash out you have to "wager" or bet 12 times more than the deposit they give you.  In my case my deposit was 50, they "gave" me a bonus of 100 and I won 225.  I couldn't collect it since I had not bet 1200 of my own money to win.  This amounts to forcing people to gamble away their winnings.

It doesn't matter if they do have the policy on their site, it is still a ripoff.  Has anyone else had experience with this?  I am now playing bingo on another site that does not have this rule.  The only rule on the site I joined is that you have to have at least 50 to cash out and you lose whatever bonuses you have when you cash out.  That sounds fair to me.  I don't know how bingoroom gets away with forcing people to bet all of their winnings.
