Have you ever been ghost/shadow banned?

I've never heard of Shadow or ghost banning until now. I think I got shadow banned on YouTube. Yesterday, I replied to a comment on a Christian based video. NO hate, NO spam. The reply was lengthy and we were simply having a cordial conversation about the Bible. Today. I received a notification that the commenter responded to my post. I went to click on the notification and instead of taking me directly to post, it took me to the main video. I tried to scroll to find my comment. I didn't see it. Then I went to my comment history and it wasn't there. I saw other comments I posted from two, three, and four days ago, but not the comment I posted just yesterday. I was really confused as why this happened and honestly, still a little confused (and frustrated)
