I have not entered the platform for a long time, but sometimes it is normal for that to happen on the sites, they may have to activate another type of marketing, not everything can be through social networks, there are newer ways they use to promote , as for example as they do in NFT games that their greatest strength is in the live presentations on Twitch.
With several influencers they can promote the site, obviously here in the forum there is a lot of reach, but if there are problems in some things they should solve them because here reputation is everything.
I understand that there could be a different method of marketing time to time, and yes I have seen plenty of people play axie infinity on twitch for example so I do agree with you there. However, bitcointalk is an important place for every casino in crypto world.
You could be a new project that doesn't care about bitcointalk and grow big, I have managed to take a brand new project that nobody knows from development to 3+ million dollars levels all from telegram and twitter without ever using bitcointalk, so I know that most business' do not require bitcointalk advertisement. However at the end of the day not casinos are not like that. At certain point we became the gamblers and people check here for seeing what is written about a casino as well so this place is a very important place for casinos. If you do not care about here, you will get left behind for sure.
