Any experience with low class players?

Sore losers is what I'm refering to. I sometimes browse peoples notes sections and see so many sore loser messages. I was looking so much and wondering when I would run into one. Aaaaaaaand today I did. Wasn't really offended by the racial slurs, as much as it made me wonder if someone had sore loser stories. And I noticed that it's usually over a rematch. Thing about my sore loser is that I accepted and HE aborted... Oh, well.
