On-line annoyances

I've played an unusually high number of annoying people on-line the past few days. One person called me an "asshole cheater" immediately after I beat him, and then no-played me. Another person didn't challenge a phoney I played (GROIT, got it confused with the valid GRIOT), and then said to me, "ur word is no good, I didn't challenge to be nice." Then I wrote to him, "if it's phoney, just challenge it right off the board." So he wrote, "it's not my style." Whatever, that's fine, but I'd prefer to play a competitive game. I didn't reply, so he wrote, "I'd rather just my opponent say 'thanks'." I didn't think there was anything to say thanks for, as I don't consider what he did a favor. On the contrary I find it slightly condescending. I was going to type this, but then I thought, why bother, and just didn't say anything. So then he wrote again, "Is the word 'thanks' not in your vocabulary???????? Now I regret it." This I found extremely irritating so I wrote back and said, "I'd rather you challenge, and not be annoyingly self-righteous." We didn't correspond the rest of the game, and then he no-played me when it was over. Well, at least these people are no-playing me. My list is full.
