Looks like
@Sophia Belle answered my question. Thanks Sophia.
I remember from the old software I blocked a guy. He was the only one I recall that ever blocked. He would answer posts in a thread, especially mine, with instead of logical counter arguments, he would respond with stuff like "Ha,ha,ha,ha,ha,ha,ha" and the like. Just a troll.
He was later banned as he was a pain in the ass to others, adding nothing useful, and just a waste of bandwidth.
Anyway, although I wouldn't see his original post, if someone quoted one of his posts, I would see the original quote and the person's quoting him response.
