+Subject: [PATCH] Federate emoji as anonymous objects
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Usually an id should point to another AP object
+and the image file isn’t an AP object. We currently
+do not provide standalone AP objects for emoji and
+don't keep track of remote emoji at all.
+Thus just federate them as anonymous objects,
+i.e. objects only existing within a parent context
+and using an explicit null id.
+
+IceShrimp.NET previously adopted anonymous objects
+for remote emoji without any apparent issues. See:
+https://iceshrimp.dev/iceshrimp/Iceshrimp.NET/commit/333611f65eb2a65b2779ece0435b5ba84bf60e99
+
+Fixes: https://akkoma.dev/AkkomaGang/akkoma/issues/694
