I think it's a explicit Ponzi site, and don't wanna to join or advertise such campaigns, but in the other hand i think everyone here is major and vaccined and even there is a section on the forum for advertising such sites, so i don't think giving negative trust for users joined just to promote and get paid some little income is really fair..
There is a section for it. So far you are correct.
But the signatures get shown under
each post that users make, not just the posts in "Investor based games".
Now imagine them going to post in "Beginners & Help", some users there aren't that experienced, they don't get a warning.
Putting negative trust on users that wear ponzi-advertising signatures is the only
warning we can give them, hence we do.
