I don't understand why a little foresight wouldn't deter people from doing it. I ragequit against one person, a QCer with extraordinary luck, and I've felt rotten about it ever since, in spite of my opponent's "bullshit" tactics.
Then again, I guess asking "Why do people do things they're going to regret later" is a stupid question itself.
