SHADOW BAN
I read about placing comments on (other sites etc) being made invisible to others except oneself and how they can simulate a page (something like that). I think I've been experiencing things like that, and auto censorship on youtube .
It is called a shadow ban. On some forum software it is called a hell ban. All forum software can do it. Once activated, a user can see their own posts, all the while the posts remain invisible to anyone else. It works by identifying the computer via IP and log in. The goal is to get people to waste all their time writing what will never be read.
