I agree with Ms. Class. Don't trouble yourself too much with it. Most people sending it in left out the exact reason for why they nominated others. With the data loss and crappy memories I was always glad if I got something like "you know the one where he/she blabla." So even if anybody had included such information it would still be a horrible job to pinpoint the exact post in the exact thread (which aren't around anymore.). Most seen is "<nick> really irritated me once with his post... ehm which one was it again?"
Myself, I voted on somebody who made an irritating post once (of which I can only remember who did it, not what and where. Just the memory of being extremely irritating at that moment stuck around. No not you Syrion
), yet isn't an irritating person normally. Maybe others hold a grudge against you, which might be why they saw it as irritating. So you've got difference between that as well. Not that you should become worried about people having grudges against "the evil admin from hell", cause he's doing his job and pretty well in my opinion.
So if it's curiousity driving you: I don't know which post. Sorry. Wish I did.
If it's feeling slightly hurt by it: Don't worry so much about it. It's not worth worrying and probably not a big thing anyway.
Right, I guess that's enough for this serious post. <insert comical laughter here.> Keeps the world well balanced.
