Like seriously? Are you serious about these things you just mentioned? Having those apps deleted doesn't grantee one that the itchy spirit of gambling would go off. Is like you saying a drunk should wash off his drinking bottle, try not to remember the road to the beer parlor. It won't work that easy in terms of gambling, but "Or you go broke; not having money to stake will make you to never go back". that would do and even change the mindset of some gamblers, I think.
