13 weeks to move the stake are a long time, I was thinking about something going into effect in a shorter time. But yes, balancing it in a way that doesn't hurt valid rewards too much while still affect switching accounts would be difficult, and trying to enforce a culture of constantly looking for other authors to reward could backfire by annoying users.
I definitely do not feel like I could come up with a working system, so for now it's just a slight hope that keeping the idea around leads to someone else doing so. Until then we'll unfortunately have to live with the situation that those battling the abuse do that with a personal cost.
I hope this part of the community has the longer breath than the ones who deserve their rewards to be reduced.
I didn't mean that moving stake would be the only evasion, but using various accounts in a round robin nature to obscure the relationships would be enough to evade, temporarily, for 13 weeks, and then after that a whole new set of accounts could be used.
Anyway, I'm probably long term bearish on the global reward pool so I hope we can see all of these measures including the minnow-hurting low-end curve as temporary stop gaps until we can move to community-specific pools which can decide on whatever sets of rules (at least within allowable parameters) that work for them, not trying to force one approach onto everyone.
