@kirby @DutchBoomerMan @paula @PeachySummer If you have regular authorized fetch mode enabled, the instance checks the signatures of incoming GET requests on objects and fetches your internal.fetch signature if there's none in its database. If you disallow viewing local statuses in adminfe, I think what happens is that authorized fetch mode gets implicitly enabled *plus* your instance just stops attempting fetching signatures of unknown actors that request objects. How I fixed it on my side is a trade secret but if you have an idea how federation works, I think you'll figure it out.
