So here are the stats for your outgoing and incoming votes (by weight) over the past 100 days and mine. Personally someone up voting themselves with a few $1 (or less) votes (while abusive to many) is slightly abusive in nature but nowhere near as bad as the bigger guys doing it. Remember by weight means that if you upvote yourself 20x at 100% and someone else upvotes you 40x at 50% then they have given you between 49.897215469% of your votes by weight and you have given yourself 50.10278453% of your votes. You decide what you make of the numbers these provide though. I would prefer a few thousand minnows upvoting themselves, and distributing the rewards over a large population, over a single user getting that reward... personally

Btw, the calculation for finding the amount of voting done by weight is a little more complex then what I did (rough approximation) and is supposed to take into account the SP of the voters as well, I didn't in my hypothetical situation.
