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.
we don't know if there's a cost to maitain an account (monetary cost or maybe some extra difficult or time needed by the support, I don't know) but in general I'd agree with you
it would be better if the accounts are not deleted or banned after innactive use
it's normal to do something for a while, stop doing it and come back again even if after many years.
