Self exclusion lasts as long as the period chosen at the start, commonly six months, one year or five years, and some schemes offer a lifetime option. It is not permanent unless that option is picked, but no one can cancel it early: a temporary self exclusion runs its full course by design. Once the period has expired, access does not return by itself on most schemes; the player has to ask for it, often after a cooling off period.
To self exclude from gambling, a player fills in a self exclusion form with the operator or, where one exists, a national scheme that covers every licensed site at once. A single online self exclusion usually covers only that operator and its sister brands, so excluding from all gambling sites needs the national scheme or a separate request to each. Whether self exclusion includes online gambling, venues or both depends on the scheme, and its terms say so.
Responsible gambling is the set of rules and tools meant to keep gambling a pastime. The usual tools are deposit limits, loss limits, session reminders, time outs and self exclusion. Many operators employ a responsible gambling officer who handles these requests and watches for signs of harm, and some countries fund a responsible gambling council that sets standards and runs campaigns, including an awareness week or month each year. Whether responsible gambling exists in practice depends on how firmly those tools are enforced.
