File Cross-Referencing
KYC checks are the final backstop. Each time you submit a passport, driver’s licence, or utility bill, the document is scanned against the entire active user base. Even expired IDs that were provided before and rejected can tie two profiles if they contain the same photo or document number. I consider this layer particularly effective because it detects people who use aliases but can’t forge real government‑issued documents. Once a duplicate document turns up, both accounts are permanently suspended, and all balances are invalidated. I have not uncovered a single verified case where a player reversed a document‑based multi‑account penalty at Crown Pokies Casino. My advice is simple: never upload an ID that’s already been used on another account, even if that account is yours and you think it’s dormant.
