My concern is that "grey area". It is a big deal righ now, specially with the whales that vote only a couple of authors, the use of bidbots and the "THIS IS TOO MUCH REWARDS!!" kinda war we just had.
All grey areas.
I don't know how good is this for investors and new users...
I know. If I personally had my own SP to do with as I wanted I'd be flagging some of it. The problem I find with the flag wars like the one we just had is that when it is done publicly it goes over board. Quietly flagging down rewards that someone thinks are over valued is a better way to go. Especially if there does not seem to be any proven abuse on the part of the person receiving the votes & flags.
On the other hand it doesn't draw attention to the problem.
