Like you said why would they even allow me to deposit and play on the site for almost a year if I was breaking their rules. They only make this claim when it comes time for the player to withdrawal winnings.
You make it seem like this is something out of the ordinary?
Do you know how any casino/gambling site works? They wouldn't just randomly go through all of their account on a daily basis.. It is only when something has happened that they look through it and that's how it is and how it should be. When you and others say things like "Why would they let me play at their site for x amount of time without stopping me" it sounds like you are advocating something similar to stop and frisk, lol.
I'm sure FJ will post more details on this case shortly, in the meantime you should present your case in a civilized manner to get the best possible response from FJ and the community.
