Can you share an example activity which Akkoma sends to Lemmy? Ask the admin or developers if necessary.

Here is one: https://idiomdrottning.org/notice/AeZ9NBAV11Qwabte7M that didn't show up on https://feddit.de/post/8519320

one more: https://idiomdrottning.org/notice/AebHdnFGP0CtGWThQm for https://lemmy.nz/post/6501778

I was only able to fetch the note object using curl -H 'Accept: application/activity+json' https://idiomdrottning.org/objects/6db9e809-b898-4fa2-89b7-e4f06c439a91 | jq. This one passes Lemmy tests just fine. Can you send me the actual Create activity? Also check the Lemmy/Akkoa server logs for any error messages around the time of federation.
