Yes, the Mostr bridge seems to be fundamentally broken... I've told Gleason about this and he responded with a expletive-laden tirade, so I don't think he's in a mood to fix it.

Momostr actually kinda works, AFAICT, but it's an anonymous dev.

I totally respect wanting to have a "Nostr-only" experience and just blocking the bridges completely... My concern is new users who see and interact with these posts just like they're any other Nostr posts, not knowing that the "phone is off the hook" on the other end.
