I to be honest would suggest to delete everything of lemmynsfw at some point, would also be better personal data wise, so it doesn't sit there forever.

Just shut it off, who cares

It’s awesome that you try to keep the old site alive as archive, but if that means that the new site is throttled after just one day because the weekly quota was eaten up by the archive … I don’t know, man.

Maybe create a static dump of the site’s rendered HTML and images and distribute it as torrent?

I would suggest using an account from another instance to access the communities, federation is working, the ui is just very very slow
