Gamblers that are having those problems need to do some serious soul searching and answer a simple question, can they really control their gambling and they have been lax on that control or they do have a problem and they cannot really control themselves anymore? If it is the former then they really need to step up their game and control themselves by any means possible, and if it is the latter then they need to recognize that even if gambling is something they enjoy greatly, the time has come to leave it behind for good.
Most gamblers who have gambled too often have probably experienced a loss of self-control in gambling, so they only increase their problems even more. If they don't immediately solve their problems one by one, they will only get deeper into gambling without being able to get out of gambling. If they really want to exclude themselves from gambling, they must really be able to control themselves well and be able to get rid of the desire to gamble. If they can do that, they can use the self-exclusion feature well and they won't even use that feature but control themselves. That will help him reduce his desire to gamble.
If you're a gambler, then control and manage how you're gambling before it get worse to the extreme stage, also, if you're privileged to see someone gambling in the wrong direction, take it a responsibility to call them into order, some things were better done or dealt with in the early stage before they got worsened, having desires for gambling is not getting yourself harmed by gambling because if ignorance or lack of self control while gambling, the gambling platforms will not control you, it's your own responsibility to do so for yourself.
