Richard Nikoley found out that his posts he submits to Reddit got shadowbanned because somebody reported him for submitting posts to his own site, which is a legitimate use of Reddit.
Err, wait. What’s shadow banning?
You can Google around for shadowbanning if you like, but essentially, it’s a means whereby someone is banned, so their posts or comments or whatever don’t show up—except to them (uses their IP address and/or cookie to tell when they’re there)
Passive aggressive moderation.
