I think he shadow-bans people with negative comments instead of deleting them. So basically it will look like it’s still posted on your end, but to everybody else it doesn’t show up. So nobody can see it except the person who posted it.I had no idea that he deletes the negative comments. At least he has to read them before he can delete them.
You can tell by signing out of YouTube and checking if the comment is still there.
It happened to me once- so now I have a second account on there
