+        ⚠️ If you're reporting an interoperability issue with a **closed source**
+        ActivityPub/Mastodon client or server, please report the issue to the
+        developers of that client or server instead. Without access to their
+        source debugging the issue is difficult for us. Since GoToSocial is
+        open source, developers of closed source implementations can run a copy
+        and autonomously debug the issue. We'll gladly address any bugs they
+        raise with us.
