I am 1 that feels that a person should take responsibility for their own actions. Even if they did block you, would you have actually stayed away or would you have looked to find another way to get back on the site? What if your bets had won, would you still be making this thread? Or would you have lost the winnings and then made this thread hoping that no responsibility falls to your shoulders?

Sites offer self exclusion and should exclude a player when requested, but so many look for ways around it once they do it. In the end, you have to rely on yourself to decide not to gamble.
