That has been happening for a long time, but I only noticed it recently. If I had the time, I would run the numbers on it, and I bet it would show a HUGE majority of ghosted comments to posts from leftists, showing that there are actually far more conservatives that it would appear. You would think that if they are going to block such replies, they would also block the record of their blocking, but perhaps since it makes conservatives THINK they have posted, and it appears to them when they post it, THINK that others are seeing their posts. I think back to when I posted all those memes and there were very few comments, and those were probably made when I first posted, with a later ghosting of my posts.
