+                        Conduwuit servers currently do not federate due to a bug with IP caching. This server
+                        also has a dynamic IP (although it does not change often), so there will be more federation issues
+                        with Conduwuit. Additionally, transfem.dev intentionally blocks all federation with this server
+                        due to interpersonal conflict on if a homeserver should be banned from everywhere.</br>
+                    <small>
+                        TL;DR: we have some federation issues with Conduwuit along with at least one intentional block.
