You could be correct, you might be wrong--time will tell.
Hate to say this, but I think even some of the best members here are motivated to post (or at least post
more) because of signature campaigns. That's a feature that's unique to bitcointalk as far as I know and it's a major driver of traffic here.
In that
link you sent me, you can see that forum traffic has dropped significantly in the past couple of years. I happen to think that's at least partially the result of the merit system. It used to be that someone could create his own farm of accounts and rank them up to Legendary status simply by posting enough and the passage of time--and then they could either sell the account(s) or earn the max in sig campaigns with the highest rank.
Nowadays that isn't possible, and I think a lot of people have given up trying to make a living on bitcointalk. Notice that you don't see many threads in Meta anymore bitching about how hard it is to earn merits. Meta used to be
full of them. Part of me says good riddance, but I'd hate to see signature campaigns disappear entirely. That would almost certainly happen if traffic to bitcointalk dropped so low that it no longer made sense for anyone to use members' signature space for advertising.
I started a thread about posting while wearing a sig:
https://bitcointalk.org/index.php?topic=5216979.msg53586174#msg53586174But paid signatures are not new, I was wearing one on a Suzuki Bandit board before satoshi even thought of
BTCAs of now I only know of 1 other place that still has one, and it's all about gambling / casinos so it's probably pulling from the same bunch.
They went invite only late 2019 due to some.....lets put it this way....legal issues due to promoting gambling... but I just looked in and the sigs are still there.
Not sure of the pay rate vs here.
