I'm not sure you have really checked different bet sites and casinos to really know if they put up ads about the dangers of gambling. It's always written boldly when you log into legit bet sites and casinos to gamble responsibly. A lot of casinos are willing to curb gambling addiction by blocking the account of gamblers when it's getting out of control but of course you must reach out to them first for them to know
In reality, few gamblers read warnings about the dangers of gambling. Most think that it will not affect them.
As a rule, people with gambling addiction do not want to admit even to themselves that they have a problem with gambling addiction, so it is not worth expecting that many of them will turn to the gambling platform for help in blocking their account. Only a few will take this step, but I believe that if a person understands what their problems are and has found the strength to fight their gambling addiction, they will be able to control themselves independently.
