Is there any rational explanation behind the fact that a Bitcoin forum -I repeat, a Bitcoin forum- is full of casino signatures?
It's quite simple: companies advertise to earn money.
Do you think that advertising on the forum does not bring money to the advertiser?
The cost of advertising on the forum is probably high due to the fact that it is difficult to control the performance of this advertisement. It is true that we have the number of posts and visitors, but is this information so clear that it helps to understand whether the campaign is advantageous or not?
The amount of clicks the campaigns receive, where the traffic comes from, and the performance gains in SEO rank are all very easy to measure. Probably these 3 (and a few more) parameters are monitored by all those advertisers when they decide to continue to campaign or not.
There isn`t much need to display number of visitors per month etc on this forum. I don`t see websites doing that... there are other and more efficient ways to measure those metrics.
