It creates short term divisions, mainly those of greed vs using curation the way it is meant to be used, how the whitepaper states it, the reason downvote mana exists and why rewards have a 7 day window to be adjusted before payout - which then no one can take away from you once it crossed that window.
We've seen many of these schemes over time, they eventually fade but cause a lot of noise shortly, most people won't remember them after a month and curation goes on as usual. There are some who slip through the cracks and become harder to combat over time because it affects so many authors, but you know, nothing is perfect.
