It is a lot of work to investigate witnesses. BTW, I am pretty happy the witnesses aren't all on the same page. It's why voting for those you feel best represent you matters. Vive la difference!
That onerous burden of witness voting is why I set my proxy to @krnel. I did that some time ago, and chose him because none of the witnesses he votes for were running bidbots, unlike @therealwolf and @themarkymark. I have always vehemently opposed botting, and made sure my witness votes didn't go to profiteers.
