Gambling regulators in the Netherlands will boost fines for online gambling sites targeting Dutch punters without a local license.

On Friday, the Dutch Gambling Authority aka the Kansspelautoriteit (KSA) announced it was boosting the minimum fine for unauthorized online gambling activity by €50k to €150k, effective Aug. 1, 2015. The KSA reserves the right to increase fines to a maximum of €810k for repeat offenders or those engaging in particularly egregious violations.

The KSA considers various criteria when deciding whether to crack the whip, prioritizing enforcement actions against operators using a dot-com domain, offering a Dutch-language option and advertising with Dutch-focused radio, TV or print media.

The KSA also takes into consideration the number of websites and types of gaming offered by a particular operator, the maximum prizes on offer, the maximum initial deposits and the size of any deposit bonuses. The KSA’s history with individual operators – whether it has previously issued warnings or levied fines – also helps determine the severity of the punishment.
