Thanks for the info, very useful. I will think about it. It sounds expensive thought. Maybe it is giving result for Casino, since they have limited options (no google or any other regular ads). But for my project, I am not sure anymore.
No worries, it's better to know beforehand since it could be a costly mistake should you advertise only to find out later.
If you're looking for a more affordable choice, there is the
Bounty (Altcoin) which you could pay in altcoins or tokens but generally the qualities of postings are much lower unless you are totally fine with the quantity > quality, as that subforum is basically for those that either are ineligible for signature campaigns or for simple tasks.
One more way is to find some popular or well-known members' avatar and/ or signature space for rental. Those are in the
Services board.
