Created by the United Kingdom’s Gambling Commission, Gamstop is a self-exclusion scheme for all UK betting sites. A number of online betting sites have not applied to join Gamstop at this time. You are able to reverse your Gamstop ban if you self-excluded by mistake, however you will need to convince Gamstop that your decision to self-exclude was a genuine mistake. Some players who have blocked themselves from gambling in the heat of the moment have managed to later have that block removed.
