LOL - this is a joke right?
eCOGRA are a regulatory commission. They provide more research to help the player, but ultimately it is the player's decsion where to play and the player takes the responsibility. What eCOGRA will do is help you when you have a problem, and try to assist you in making the right decision.
Having been in to see how they work recently, they have a very thorough way of dealing with complaints and any of the casinos they seal who act out-of-hand would soon find their seals revoked. Interestingly, most of the issues from what i can gather come from fraudulent players, bonus abusers, or players who played a bonus without understanding the T&C's.
What they do is much needed in my opinion. We've seen this sort of post before from players who took a complaint there and had a ruling go against them (see above). I think most posters here would agree that the casinos on the eCOGRA list are reputable casinos. I dont believe any of them would not pay out unless they had good reason to suspect something wasn't right.
