Regarding whale votes, they vote differently according the the stake of the votee, generally.  If they are voting for a whale, they vote with more than 50% of their stake weight, but if voting for minnows, they vote at 1% or so.

Again, oligarchy rules.  

It is for this reason, amongst many others, that I find @transisto's claimed reason for flagging here incredible, as in not credible.  If he really wanted to 'share the wealth' and decrease the sucking sound we hear as the rewards pool is drained, he'd be flagging whales.

Does he?  NO!  That would endanger his precious ROI; his sacred stake.

Money =/= mouth.
