From what I understand (as I have not been paying attention back then), people have requested this section in the past and thus it was added. It was probably because the threads were flooding some other section and this is exactly what would happen if it was removed. The first step would be to ban Investor-Based games altogether. That way, no other section would be cluttered up with these threads.
They should just delete this trash category, just a playground for scammers.
That's essentially what it is. A playground for scammers and
signature spammers.
I agree with you, is just that the problem with this statement is that usually investor-based games posts are usually not counted. Even if they are, depending on the post, they'd most likely get a negative trust and every known sig campaign don't allow negative trusted users.
