Oh, no… there are ghosts in this protocol! Yikes!
haha yeah it's a handy way to be able to see content from people who haven't switched over yet, but does have the issue of the "ghost profile" effect. I think it could be beneficial for there to be a NIP that describes a sort of "bridged profile" identifier on profiles made by mostr/rsslay/etc
Yeah I think we need a bunch more thought and some code around bridges and gateways.
