@manyfold Thanks, I'll be testing against it.
Follow-Accept: OK.
Comments: OK, but there's an issue with hashtags. The property name should be tag, not tags
Models: 500 Internal Server Error (example: https://manyfold.floppy.org.uk/models/LfzPs8c5)
I also tried to use outbox collection. It appears to be self-referential structure because current and first pages have same IDs as outbox:
{ "@context": "https://www.w3.org/ns/activitystreams", "current": { "id": "https://manyfold.floppy.org.uk/federation/actors/476e20c4-6014-4ff6-9831-e46ddc7fc31c/outbox", ... }, "first": "https://manyfold.floppy.org.uk/federation/actors/476e20c4-6014-4ff6-9831-e46ddc7fc31c/outbox", "id": "https://manyfold.floppy.org.uk/federation/actors/476e20c4-6014-4ff6-9831-e46ddc7fc31c/outbox", ... }
