I think there might be Federation restrictions at the Botsin.space side -- I had noticed one of my Followed accounts from there disappearing from my feeds.
visited and read their About/more pages and there's NO disclosure of their blocking or silencing policies or affected instances. Maybe contact their admin with an enquiry? https://botsin.space/@muffinista is the one.

You'll notice that the odd post does still come through - there was one today, in fact, which is what prompted me to investigate since I had previously thought the bot was deactivated when I stopped seeing its posts regularly. I also retain my status as a follower of these accounts, which is normally not possible if a block is in place. This makes me think we're not subject to such a restriction.
