Only crypto gaming sites and casinos that are licensed and approved would pop up as ads on social media platforms. Social media platforms don't allow adverts from casinos that are not approved and registered. But I don't know about websites though, people mostly come across scam casinos on some websites because they lack proper security and monitoring. I have seen so many casinos on the internet that turned out to be a scam but the ones advertised on social media platforms are authentic, people should take note of this.
