Its utter chaos some things federate some dont some federate in one direction but not the other some just mess with formatting. Someone really needs to come in and fix the whole mess. If i where to fix it id start with that flask implementation of lemmy then add whatever additional routes are required to make it simultaneously a mastodon server. The dream would be a single account that works across all federated services simultaneously federating the same post with the same comments across all front ends. Never going to happen tho sadly.
