Dutch gambling regulators have doled out yet another six-figure fine against an unauthorized online gambling operator.

On Monday, the Netherlands’ Kansspelautoriteit (KSA) regulatory body announced it had imposed a €310k penalty on Malta-licensed Casumo Services Ltd for offering online games of chance to Dutch customers despite such activity having yet to earn the legal stamp of approval from the local government.

The KSA’s case against Casumo will read very familiar to anyone who’s read similar penalty announcements over the past few years. Casumo’s website offered hundreds of online casino games, offered live chat services in the Dutch language, and allowed customers to process financial transactions using iDeal, the Netherlands’ leading online payment processing service.

This is the second major fine imposed on Casumo in the past four months. Last November, the UK Gambling Commission hit the operator with a £5.85m penalty for failing to ensure adequate safeguards were in place to protect problem gamblers from self-harm.
