When you list projects even after you know it was scam then it is very shady behaviour and not to be trust at all.
This is not abusing power,its called doing the DT work with perfection.

i agree with you this is DT perfect work and i respect it , i call abusing the reason they could tell us about scam project , if we don't remove than they give red trust , and if we get any scam project information than instant we remove that project ,
Since you are the one listing, it should also be your job to do research which one is a potential scam. Its called responsibility to make it your job, do the initiative as well because if you depend to the people around who will tell you which ones shouldn't be in the list, you will lose credibility.
