Speaking live at the annual Gaming in Holland conference, Kansspelautoriteit (KSA) leadership delivered a severe critique of mainstream social media channels, stating that global networks are completely saturated with unapproved gambling marketing campaigns targeted at local consumers.

The Dutch gambling regulator warned that compliance enforcement must look past standard corporate fines, which have proven structurally ineffective, to systematically break down the core digital infrastructure supporting black-market operators.
Skyrocketing Social Media Ad Volume Alerts
The regulator exposed a massive escalation in illegal advertising across networks managed by tech conglomerates Meta and TikTok. Operational data shared by the KSA reveals that supervisory teams were forced to transmit an astonishing 26,000 formal non-compliance reports to Meta during May alone, expanding exponentially on the 4,600 warning alerts sent out during the month of April.
The KSA’s aggressive stance mirrors parallel enforcement friction unfolding across the North Sea. Tim Miller, Executive Director of the UK Gambling Commission, previously accused Meta of taking financial gains from criminal operators, a concern reinforced by a Flutter-commissioned technical study that exposed active black-market casino transactions executing directly within the native Instagram interface. To pressure social media platforms, the KSA joined a coalition of European gambling regulators traveling to Dublin to confront tech compliance executives directly, calling for the implementation of automated pre-publication ad filters.
The regulatory friction materializes as the Dutch licensed online market hits a prolonged period of stagnation, heavily impacted by a steep corporate tax hike that saw state rates jump from 30.5% to 37.8%. The fiscal change has flattened gross gaming revenue (GGR) growth and localized player registration metrics, running counter to an average 11% growth curve experienced across alternative European Union gaming corridors.
Current data indicates the tax increase backfired completely, driving consumers straight to black-market sites and leaking €387 million annually in prospective state tax revenues. The domestic channelization rate has degraded down to 53%, meaning nearly half of every euro wagered in the Netherlands is processed by illegal brands. Amid these hurdles, operators face legislative proposals from a new coalition government, formed by Democrats 66, the People’s Party for Freedom and Democracy, and the Christian Democratic Appeal, demanding a total gambling ad ban and strict limits on licensed domain counts.
Dismantling the Infrastructure of Black Market Operators
Ella Seijsener, Director of Licensing and Supervision at the KSA, told executive attendees that multi-agency infrastructure blocks are far more effective than uncollectable corporate fines:
“We intend to break down the infrastructure around illegal providers, make it impossible for them to operate in our Dutch markets. We are open about the fact that fines are almost impossible to collect and thus are almost never paid. What is more effective is our comprehensive approach by working with hosting providers, banks, payment service providers and marketing companies.”
Seijsener implored licensed operators to step away from legal loopholes and focus on safe, transparent consumer marketing:
“I understand that advertising is necessary to make a legal market visible to Dutch consumers, but there are advertising rules, and they are there for a reason. As soon as new phenomena arise, such as streamers building themselves while gambling, it is upon you to consider these phenomena in the light of existing rules. Relying on gaps or ambiguities in legislation or regulation is easy, but if the average Zembra viewer does not see the nuance, you can wonder whether you are in the right or have simply been looking for a loophole.”
