I've found duelbits ads on Instagram and Facebook too, as well as on platform X. Maybe not as often as here, but this also depends on the viewing history which is then continuously recommended by the platform. They also attract gamblers to become customers on the platforms mentioned above, but only they know which platform is most profitable for them.

I end up wondering why most exchanges don't want to run promotions on forums. I know they already have a large client base without promotion on this forum, but their involvement in the community can help this industry grow better. bitcointalk is the biggest discussion forum they deserve, at least they need to consider running a campaign as a bonus for contributors on this forum.
