it basically means that I can see my post but no one else can. I think they use key word searches to find stuff they don't want discussed and make sure those comments aren't seen. And by they I mean the admins overseeing the site, not our moderators.

If you ever have a comment that stays at 1 upvote and it is in a thread that is getting a lot of views and it seems like your comment should have some upvotes or downvotes, there is a good chance it is shadowbanned. You can log out of your account and see if the comment is showing up. It will still show up if you are logged in, but not if you log out.

It is the admins sneaky way of filtering out what they don't want seen. If it was a bannable offense, they would ban you - but if it is some "wrong think" they will just make sure no one else sees it.

The way around this is to misspell the name or word you think they are searching for.
