All of these are “root” mounts. I don’t explicitly mount any subvolumes (they get “implicitly” mounted as folders though)

There are signing keys involved, so if someone puts up a new server but uses different keys then all sorts of federation trouble will await them.

That said it shouldn’t affect the general network, just that individual server (both the communities and the users of it)

Edit: As for switching domains on an existing server, that would be equally troublesome as ActivityPub kinda relies on domains for all sorts of IDs.

People aren’t against companies, people are against Meta. In the wider fediverse, anyway.

A while back there was talk of Tumblr potentially joining the fediverse, and it was met with neutral to positive reactions. No idea what happened there, maybe they’re still working on it, but I do not expect a “fedipact against tumblr” to gain as much steam (if any) when they decide to announce they’re ready to flip the ActivityPub switch.

(no idea if my other comment got sent out, this may be a duplicate)

Tildes was always invite only. Granted it is (or was at the time, maybe they slowed down with the influx) really easy to get your hands on one by just asking on r/tildes (or email).

Hell, the site being readable by the general public is a relatively recent introduction compared to it’s history.

You could represent booru tags as hashtags, and PixelFed already shows how image sharing can be done.

All that’s left is someone to do the hard work of patching together a booru UI for ActivityPub. Hell, considering the use case it could be a frontend for an already existing backend-only AP software like GoToSocial. That would make the implementation drastically simpler as you wouldn’t need to deal with any of the AP parts at all.

I have no idea if there was a native setting to disable it or if it was RES’s doing but I completely forgot chat even existed.
