This is Midnite’s third ASA ruling this year. Last month, the operator came under scrutiny for an ad that suggested that “gambling was an escape from personal problems”. The ASA received 125 complaints on the offending ad and the company was ordered to remove the advertisement. 

Another June ruling was not upheld.

In a separate case, the ASA examined display advertising for White Hat Gaming’s Casimba and The Grand Ivy Casino brands, which had appeared on HLTV.org – a specialist Counter-Strike 2 e-sports website – in March 2026.

Of the KSA’s update, Fuchs said: “If you [as an operator] have a clean sheet, there are some hoops, but for various modules you can just send a declaration which states that you’re compliant.”

The KSA said that applicants were previously required to detail corrective actions taken to address previous breaches and outline measures to prevent future violations.

According to Nederlandse Loterij, illegal operators currently control approximately half of the Dutch online gambling market and account for roughly 95% of online gambling advertisements, frequently masquerading as licensed providers. 

The Loterij suggested around 200,000 Dutch citizens already engage with unauthorised platforms.

Earlier this summer, the Dutch Online Gaming Providers (VNLOK) trade body initiated legal action against Meta and lodged a formal complaint with the European Commission, accusing the social media giant of failing to prevent the widespread display of illegal online gambling advertisements targeting Dutch users on Facebook and Instagram.
