I don't think scoop cares about the onsen instance. Anyone with a brain wouldn't.
Just look at the webms.

soulless npc's

If onsen filters out the oldfags who have become soulless coomers and the newfag coomers who never had soul to begin with that don't even use vrg and are just here use trash as a pool to find erp partners. Literally a good thing. They're just going to sit in the back taking up frames bouncing on each other, might as well do it in a different instance. 
The fact that they use an onsen every time essentially selling their event with sex and erp tells you everything you need to know about the people.
Let them keep doing it. 
Ignore it.
Nothing and no one of real value is lost to the onsen instances.
