Why do people waste time replying to your comment if they're just going to block you?

Their passive aggressive. They want to get the last word in and feel powerful knowing you can't or won't see what they wrote even if their not, it just presents the illusion that you lost basically lol. So their like winners in their own head and pat themselves on the backs for a job well done.

Nearly every person that's blocked me has done that, I just call it for what it is.
