The fact that this is even happening as anything other than a programatic exercise to see if it "can be done" makes me wonder if the people doing it have any real work to do. Some days I'm so busy that I have a hard time even making it in to lurk, let alone vote.
Of course, if I posted rather than lurking and had a voteBot, my experience would be significantly higher. But often, I have the same problem here as I have on Slashdot: someone has said it better and more concisely first.
I just never feel like adding "yeah" or "me too" to attempt to raise my level. It's self defeating.
Good luck killing the voteBot.
