The group, titled Dordtse Queens, was ran by eight administrators, who advertised illegal bingo games through the group and on their own personal Facebook pages, attracting almost 10,000 members.
The regulator also found that minors were given the opportunity to participate in the illegal games.
As a result the KSA reported the matter to Facebook, which promoted to remove the social media giant to remove six pages affiliated with Dordtse Queens.
It is the second time in recent months the regulator has taken action against unlicensed bingo offerings on Facebook.
In September Luxury Bingo and BSB Shop were both ordered to take their products offline, and threatened with fines if they failed to comply.
Meanwhile the country’s regulated market is up and running, with KSA issuing 10 licences to offer igaming in the Netherlands from October 1. However a technical fault with the country’s self exclusion platform Cruks meant that the launch was delayed until October 4.
Since then, JOI Gaming, a subsidiary of casino operator JVH Gaming & Entertainment Group has also been approved for launch.
