That's how they were doing on Ragnarok, but I switched server recently and got right into middlle of hunt drama. It looks like a small group of people got tired of undeserved insults by players who never spawned anything in their life and just leech of relinks. For them it's annoying to see a leecher with radar without even fisher unlocked waiting near Horizon aetherite and shouting/relinking the exact position of S rank the moment they catch Glimmerscale. So now they punish lazy and hateful community by trying to ninjakill as many S as possible. I should say they succed a lot, even with some people tracking and following them all day (instead of actually trying to spawn something themselves).
It wouldn't happen if people actually respected spawners, just look, even I was already called an asshole in this thread for hours and hours invested so they can zone in, get +1 credit to their mount, zone out and wait for next relink.
