I find I'm less inclined to reply to a post when I notice a lot of interaction from people I blocked or who blocked me

On some threads we may notice a couple messages missing and that is not a big problem but yeah when we scroll a thread and half the messages are deleted, it is like, "Okay screw this".

Kind of for the same reason one would not even bother trying to read a book if half the pages were missing or damaged.

I very seldom block anyone so more often than not it is people who blocked me first.
