Brief Summary

Considering that self-exclusion from gambling on a particular website is an intervention for and by individuals who have developed a gambling disorder, it is currently exclusively a behavioural intervention in the sense that it prevents the behaviour Resumption of commercial solicitations only in the period when gambling is not accessible in the corresponding website , through voluntary self-exclusion (where the gambler prevents himself or herself from gambling), does not appear to be sufficient to prevent relapse. Early commercial solicitations, in the immediate intercourse after the end of the self-exlcusion period may precipitate relapse in gamblers whose behaviour change is by definition recent, and who have only received a behavioural measure. The investigators hypothesize an improved efficacy as measured by reduced gambling after a self-exclusion optimized by a period of suspension of commercial solicitations extended to 9 months, compared to self-exclusion with the standard procedure. Gamblers will be randomized according to an a priori randomization list.
