Luke have you looked at other people putting self voting in perspective? link
Personz comented in the first link, 'self voting is a rampant and a huge problem', although he said I said rampant amounts to argument of the beard, I'm leaning to agreement, self voting needs to be shunned and flagged, we have the tools already, lets put them to use to trim this beard down, I think it has become a beard.

It's simply about perception, when people see others GAME THE SYSTEM, it devalues the overall experience,but I disagree with @blueorgy where he said that flagging will drive user away, I think flagging is a tool that would keep users more than drive them away, especially if people downvote bullshit self voters, personz quote the prisoners dilemma, which is exactly where we are headed if we encourage this behavior.

The naive voting process creates a Prisoner’s Dilemma whereby each individual voter has incentive to vote for themselves at the expense of the larger community goal. If every voter defects by voting for themselves then no currency will end up distributed and the currency as a whole will fail to gain network effect. On the other hand, if only one voter defects then that voter would win undeserved profits while having minimal effect on the overall value of the currency.
