@mapache There is a little problem with this actor. The server returns an HTML document when request is made with Accept header value required by ActivityPub spec: https://www.w3.org/TR/activitypub/#retrieving-objects
To reproduce:
curl -L -H 'Accept: application/ld+json; profile="https://www.w3.org/ns/activitystreams"' https://badges.vocalcat.com/actors/badges.vocalcat.com/fediverse
