Your question title makes sense but the rest is a bit confusing, so I will add what I can. You best advice is to stick with legitimate online casinos, this way you wont be cheated as the casino site will be audited by independent auditors.
If you follow the advice or casino links from the best online casino bonus page, then you will avoiding the "bad" online casinos. The page mentioned above bascially indicated that you should look for certain things that all legitimate casinos should have, such as 24/7 support (preferably toll free phone support), etc, etc.
