Shouldn't the ability to vote(up/down) begin only after a particular amount of time has lapsed since the initial post? Same is true for accepting an answer to a question, both of which you yourself have posted or is answered by someone else. I think the reasoning behind those limitations would easily apply here as well.
I want to reassure all of you that I neither passed around a link to my answer internally, nor enjoy any special privilege as far as up-votes go.
However, I can neither confirm nor deny the existence of a bug that generates an automatic up-vote for each use of the question-asker's name in an answer, hus787.
You'll just have to figure that one out for yourself. Hus787.
