Promoting a project which turns out to be scam is not worthy of a red trust (this is my opinion), except it can be proven that the user had information about the scam, or found out at a later time and did not expose the developers.
It's possible to unknowingly enter a promotion campaign for a scam project.
The topic has been under construction.
Anyway, thanks for your contribution.
