Interesting @therealwolf and thx for sharing!
In another comment @reggaemuffin more or less brought up the same issue, but it all has to do with the way the SP is distributed.
What I'm thinking now, is by limiting the amount of slots - maybe 30 slots isn't the right number???* - that any account can use to either approve / disapprove witnesses, more balance could be added and a mechanism to express support or disagreement to any witness' behaviour.
Do you have other witness voting mechanisms / ideas to deal with the concerns you mentioned?
