Betfury still is popular but my guess is this is because they were doing a bounty campaign in the forum but now, seem not a very exciting time anymore and the volume of the token on exchanges is no way to make a price change.
I doubt there is any correlation between the campaigns that Betfury ran earlier on this forum and their current popularity, as well as the daily BFG trading volumes on the exchanges. If advertising on this forum had really significantly affected the popularity of the project, Betfury wouldn't have abandoned this thread and would have been constantly active here.
I am sorry to disagree with some of what you said,
First of all, the signature ad advertisement Betfury held on this forum really did contributed significantly to their popularity on this forum at least, I don't know about their popularity out there, but on this forum, their advertisement did help make them popular.
And I sure agree with you that, their Signature ad campaign on this forum has little to nothing to do with the current trading volume of their token(BFG), but like it or not, their inactivity on this forum have made them loose some holders of BFG, for example, I myself was a holder, but I sold all after they stopped being active here, and have stopped posting about the current developments of BFG.
And lastly, their abandoning this thread does have everything to do with them no longer running a signature ad campaign on this forum, if they still had a campaign on, they wouldn't have left, regardless of the fact whether their presence on this forum made them popular or not.
