Not really, gambling advertising has become popular and developed only in the last few years, to be precise since Covid hit the world, because people can't leave the house to gamble, So many gambling industries are switching and implementing Bitcoin payment features, actually the most popular gambling sites are not Bitcoin.
That's one of the reasons the forum is dominated by gambling advertisment but another is the atmosphere the forum has against crypto projects.
Nobody investigate the gambling sites that much being advertised here unless a scam accusations comes up but when it's a crypto project it gets immediate attention and digging begins, which is applaudable from the community as it keeps us safe from scams.
But it also chase away potential adevrtisers as they don't think they'll find success on the forum since the forum is proBitcoin (not saying altcoins aren't welcome) but I don't think they'll find alot of success for their campaigns.
Even the bounty section is drying off because the interest of the community has gone pass the days of altcoins. Only the gambling sites are benefiting more, mixers that would've also benefited too has been banned.
