I don't think it would be anything beneficial in terms of nyfco/iketog itself honestly speaking, most of these roommate-sharing sites tend to go under the radar because it's not overly talked about in public so this one especially stood out because people (especially the nijisisters) couldn't stop acting boisterous about it and practically treating it as their own /vt/, another instance of a similar site shutting down also has happened once and the site admin of that site nowadays is only laying low in semi-public discord server.
My main gripe with nyfco/iketog is that a blatant holo-anti runs the site and has proven to be willingly giving out private info like real name and such, also the admin practically left the comments section on its device and is what makes the site go to shit-stirrer grade fast.
I don't care about sharing roommate stuff that's already on the internet but I think pointing people out with real-life information is a bit too on the nose especially when it's about VTubers who don't do flesh streaming as their main content.
The admin themself is probably anti-holo, too. The only times they would update an individual page on the site after getting in trouble the first time is when a holo girl got drama which was then used to make said drama worse.
Anyway, the rat will never escape the meme.
There actually is a lot of moderation going on over there believe it or not, I think like 50 comment pages of the advent discussion got wiped randomly, the biboo stuff might or might not be the reason for that. Surprisingly the advent page was overwhelmingly positive comment wise (at least up to what I have read), if you dont count the biboo stuffs. The sisters actually rarely ventured outside of their containment thread. There were many threads with less than 10 comments
The modders also actively protect the sister over at the Nina page and wipe blatantly obvious anti-sisters comment
There was moderation, just in the opposite way of what you want.
