Thanks for your help. Checking just now, I’ve not blocked them as a user, nor their instance, nor their respective posting communities. Indeed, when I look at their direct acct, I see plenty of their recent FS posts: https://discuss.online/u/m_f

Oddly, when I look at that same acct, only formatted through my instance, their username seems… reversed? https://piefed.social/u/m_f@discuss.online

Anyway, for some reason all their SMBC comic posts seem to show up everywhere for me. It’s just the FS ones that don’t. oO

Maybe it’s some kind of handshake issue between my instance software (PieFed) and theirs (Lemmy, it looks like)
