Yeah right!- Fake approval.
- Advertising a high risk/scam project for the right amount.
- Blocking the access of those that got scammed to your community.
- Just want to profit for yourself (you don't care what happens to other users).
how i know if the person who want advertise is scammer or no ?
Although there's no way to know it (100%) for sure, you can decrease or eliminate the chances of promoting scam projects by having a screening process (something I'm sure you don't have [even if you pretend, I'm pretty sure you don't know the different aspects of it]).
