I am of the opinion that since gambling sites are mostly online and some has adds that pops up as advert on visited site, one should be able to disable or change their browser settings by blocking casino adds and as well disabling gambling sites on their browser settings so as not to gain access to it anymore till the number of days they deem fit to their resolve. This was just a little tip I gave as a possible solution. I had to put it up here for further discussions so that the bigger community can see it as well.
If you feel or think here is not the right place for this you can say it. I am open to corrections as we all are here to learn.
But will disabling gambling ads stop someone from gambling? Because I don't think so, since such individual can still visit such site even when ads have already been blocked, as blocking ads do not stop a site from loading. So I think the only way one can stop from gambling addiction is simply when someone recognize the harm his/her gambling addictions is causing him, and personally decide to change by himself, while any means that will tempt him to gamble being taken away from him till he fully recover. As there is nothing good as self repentance.
