Oh, i actually didn't know Kbin (despite these posts lol) was being seen from Lemmy. Iirc when i first saw Kbin a few days ago, Kbin could see Lemmy but Lemmy couldn't see Kbin. Ie it's like it was a partial federation.
I'm curious on if that was accurate and if it was, what caused it in a technical sense. Given i'm a dev working on some ActivityPub stuff, i'm quite interested in it. Though i've not yet used the spec, clearly hah.
