I have collected a bit of data now from the 1-2 I get of this type, and my data agrees with yours -- the issue here is that we do not need anyone driving off new people that are hard enough to retain just for the purpose of doing so. In a decentralized setting perhaps nothing can be done, but do we KNOW that nothing can be done?
On the other hand, more ACTUAL curation is a more uplifting way to counter this foolishness ... so, perhaps the energy is best spent there.
