• The intent is also considered, was the user wearing a signature when the post was made? Does it bring them any form of benefit, or were they just excited about sharing some new information.
I also heard the opinion that "no signature means the user is innocent", but this does not work.
The user can shill the project or increase the number of posts.
It is now I understood @Upgrade00 reply. It is assumed the intent is to make money if the user us wearing a signature. And if no signature, it is assumed the user just wanted to impress readers.
