Why do people block other people in the middle of a debate?

Or start insulting you? I’ve encountered this loads. I’ll be replying to them in a nice way, just trying to prove my point of view then they start insulting me calling me names, or they randomly block me to stop me from replying to their argument. Especially if they run out of points or they’ve “put the last word in.” What’s up with the blocking and insulting?
