Come on now, you are rejecting traffic to sites you dont want to visit? Just dont open those websites at all.
Gambling addiction is hard to come to terms with. I think spending time outside your own gambling "man-cave" might have better effects. Look at things that you might have given up during this period while gambling just so you could gamble.
Often times we give our addiction preference and cut down relations and friends which are good for us. Try visiting those back and see how it helps. Otherwise professional help is always there.
