Nice work @crokkon - resteemed :)  I would be curious to see the correlation between bid bot (paid vote) use and self-voting - I would assume it is high, as getting a self-vote in before large paid votes is one of the best curation ROI games in town particularly when you can wait to decide what post to pay for votes on until after you manage to get your own vote in at the optimal time.  Any way you could run a quick query using your bid bot list to see what % of posts upvoted by the self-voting and low-diversity voters *also* end up receiving paid votes, vs. what % of posts NOT upvoted by self/low-diversity voters end up receiving paid votes.
