Lemmy community search shows results for ghost communities that have been gone for over a year (links.hackliberty.org)

I did a search for communities with “history” in the name. It came back with !history@links.hackliberty.org even though that instance has been down for over a year. If I did not already know of that instance going down, I would just post there expecting my post to be seen, because there is no indicator of when the server was last up.
