Self-Exclusion

Self-exclusion is a responsible gambling mechanism that lets a player bar themselves from gambling with an operator — or, via national registers, from an entire licensed market — for a fixed period or indefinitely.

Self-exclusion operates at two levels:

• Operator-level — the player excludes from one brand (and usually all brands of the same licensee); the operator must close access, suppress all marketing and refuse re-registration for the exclusion term;
• National registers — centralized schemes covering every licensed operator in a market, such as GAMSTOP (Great Britain), Spelpaus (Sweden), CRUKS (Netherlands), OASIS (Germany) and ROFUS (Denmark). Operators must check these registers at registration and login and block matches in real time.

Technically, this means register API integrations in the login path, marketing suppression across CRM and affiliate channels, and duplicate-account detection to stop excluded players returning under new details.

Why it matters: letting a self-excluded player gamble is one of the clearest, most sanctioned compliance breaches — often with mandatory stake refunds on top of fines. Register checks belong in the platform core, not in bolt-on scripts.
