Never mind, the person I have in mind has in fact been downvoted at least once. No negative-karma comments.
I've definitely gotten 500 karma while not having any negative comments in that span, I wouldn't be surprised if someone has pulled it off, though obviously the first 500 is harder.

So maybe we should celebrate failed attempts more often ... I for one can't think of anything I've failed at recently, which is probably a sign that I'm not trying enough new things.
So, what specific things have you failed at recently?
