I get that position, but it just feels like it's a bit more nuanced to me - although I'm not sure of a fair way of deciding the cut off line and it obviously has to fall somewhere.

I have no idea how many accounts may fall in to this category - but if an account was voting for say 3 sun/puppet accounts, but also voting for 27 of the previous witnesses; that doesn't really "feel" like an attack.
I'm guessing however that most people took one side or the other - I have no data to back that up though.

@themarkymark I know you're curious about things, and back that up with quantifying data - have you done any sort of analysis of patterns of voting? Are there many cases where voting was ambiguous in terms of a split between the two positions? Or did most votes fall on one side or the other?
Is my hypothetical example likely to be affecting so few users its not worth the effort?
