I saw that the community i moderate is available on blahaj.zone, and it has pulled some old comments, but new ones did not federate. There is also an old stickied post still stickied.

I assume somone from that instance had the c subscribed at some point, but then unsubscribed, so new comments and actions did not federate. If now somebody on that instance would subscribe again - will the obsolete sticky post just stay there forever? Because i am not sending the mod activity again to unsticky it?
