If a person cannot control his self himself, then even if he not only logs out of that platform but also deletes his account on that platform, no one can stop him when he wants to gamble, in which case he can also change that gambling platform.
You're right. He can gamble again in other gambling sites. We have many gambling sites, it will be very easy to create an account in a gambling site. However, it isn't about the chance to return but how he can change his attitude. If he finally can have a better self-control, it is not a really problem to gamble again with a better approach/way.
Nowadays, many casinos have introduced some additional features for responsible gambling and these are self-exclusion, cooling off period, and temporary account suspension. In the case of these, the thing I mentioned above is more noticeable when a gambler gets a temporary account suspension for irresponsible gambling or he uses self-exclusion himself, then when he loses control over himself and often changes the platform to gamble.
Those features only can work properly if the gamblers are aware of the possible problems of having lack self-control. If the gamblers aren't aware or he don't care about it, the features can be useless. IMO, the main point is how the gamblers to have proper mentality in gambling. I think there should be a certain test for every new use to join the gambling site. It is intended to ensure the new user having good mentality to join the gambling site.
You said it, money willing to lose and discipline, for me they are the two pillars to be successful and not only in the game but in any area of life, I personally have always said something, if we are people who are always going to generalize a strategy for me this should be the base, start with ourselves and then worry about strategies, about understanding certain things about the game, but never losing this control discipline.
Yep. Discipline is always the key to be success in everything. Those gamblers who can be disciplined and always stick with the plans, they will be safe from the possible problems such as addiction, being stressed, and etc. But no doubt that it won't be easy to be disciplined because sometimes there should be tough challenges.
