Self-Exclusion
Self-exclusion lets a player ask to be blocked from gambling for a set period, and operators must honour and enforce it.
What it means
Self-exclusion is a responsible-gambling tool that lets a player voluntarily bar themselves from an operator — or, through a national scheme, from every licensed operator at once — for a fixed term that can't be cut short on a whim. In the UK that scheme is GAMSTOP; Spain runs the RGIAJ register through the DGOJ. Once a player is on the list, you must block signups, deposits, and marketing to them.
Why it matters for operators
Letting a self-excluded player slip through is one of the fastest ways to draw a fine or lose a licence, and regulators actively test for it. The hard part is enforcement across brands, devices, and duplicate accounts, which is why it leans on strong KYC and a PAM that checks the register at signup and deposit. Treat it as a core part of your responsible-gambling program, not a checkbox.
Example
A player on GAMSTOP who tries to open an account with a UK-licensed brand should be blocked at registration — if they deposit and lose money instead, the operator is usually liable to refund it and answer to the regulator.
