But people have a habit to change their decisions. 35 years ago I wanted to be a firefighter. After many years, I have chosen different profession. People opinion change with time, after a decision. Not saying that casinos should immediately welcome their former clients who have chosen self exclusion, but will it be bad if a gambler returns after 10 years? From ToS - yes, as solution would be having another account. From moral point of view - I would give a chance if a person really wants to return.
