Are there #activitypub networks inside non-clearnet networks 
I have a question about #activitypub :
Is there a method for: Following from account xyz only post of a certain type (e.g., images) or a certain hashtag ( #abcd).
As an example: I would like to be able only to see the comics that a comic artist posts, but not their further opinion. (type is only image)
Another example from the sender side: I am a music group and I would like to invite people to: "Follow #concert_announcement for @mycrazycoolband"
Maybe @benpate knows about this?
The beauty of #ActivityPub
Yes, Loops federates, and admins can enable any remote instance video posts to appear in local follower feeds AND you can even include them in the For You page ✨
Fediverse account backups via 3rd party FOSS service
Personal Archive Node (PAN) is quite brilliant, its compatible with most fediverse software already, and uses a dual strategy for data backup, with one being adaptable to most fediverse software via adapters.
While not exactly ideal, PAN solves the issue of unforseen instance shutdowns in a short term fashion, while paving the way for a long term, more efficient solution ✨
More details soon.
