Hiya. This isn't anything to do with pawb.social's operation specifically, but rather the entire Lemmyverse. With the release of v0.18.0, it seems like a regression was introduced and Lemmy's ActivityPub implementation is now a bit broken. Federation between servers is very dodgy, and may have something to do with different versions of Lemmy communicating, e.g. 0.17.4 <-> 0.18.0.
Edits, posts, upvotes/downvotes, etc are not very consistently federated, and I've noticed that there's been a lot of dropped interactions. Of particular note, Kbin hasn't received any of my activity in 4-5 days now, and Beehaw seems to also be struggling to receive or send activity.
More information about this regression is available here:

With 0.17.4 being a websocket nightmare, 0.18.0 not having captcha, and interactions being frequently dropped, we're sort of in a state of chaos at the moment.
