There are cases in this forum (scam accusations) where casinos and gaming sites with Curaçao licences have serious scam accusations against them but the Curaçao authority that issued the licence did nothing to resolve the issues. They have no real authority to force casinos and gaming sites to do anything to resolve complaints. It is just pointless.
Curaçao licences are just shit tbh, they are just scraping up the money and providing their licences to sites even without verifying whether the site operates under their respective terms or they are doing shady things. As you said, Curaçao authority never involves themselves in any disputes I have ever heard which comes under their hood. We cannot trust any gambling website based on licence alone because even with such an 'established license' can scam us and some websites which are already established but do not have a license, serve their users honestly for years.
