The public prosecutor has reached an out-of-court settlement with all but one online casino operator based in Curacao that failed to conduct verification checks.
As a result of the settlement, 11 of the 12 operators paid a fine of XCG 22,500 ($A19,000) for each online casino it operated.
Curacao is the centre of much of the world's unregulated online casino and betting outfits and is the licensing headquarters for Australian-owned crypto betting giants Stake and Shuffle.
None of the operators involved in this latest enforcement were named by the prosecutor.
Despite its obligations under the settlement agreement, one operator failed to pay its fine.
For this reason, the settlement agreement between the prosecutor and the casino has been cancelled.
The operator will be summoned to appear in court.
According to the prosecutor, the outcome of the criminal investigation confirmed the suspicion that online players were able to create an account and subsequently deposit funds without their identities being verified.
“An adequate know your customer (KYC) procedure, which includes identity verification, is essential to prevent games of chance from being misused for illegal activities such as (identity) fraud or money laundering,” the prosecutor said.
“It also serves to prevent minors or gambling addicts from using the services of online casinos.”
