The logic is a little tricky to get right because there's a set sequence of steps that needs to happen in order for the group sync to succeed. For example, between NodeBB and Lemmy: NodeBB admin tries to follow a Lemmy community NodeBB marks the follow as pending Lemmy records NodeBB as a follower Lemmy community tried to send an Accept back NodeBB marks the follow as established. If steps 1-3 succeed but 4-5 fail, then posts might be sent to NodeBB, but NodeBB will silently drop them because they're not addressed to anyone it thinks is following the sender. @freamon thanks for the heads up about lemmy's accept shenanigans, I'll take that into account... or maybe ask Felix about it. @arachnibot @FrankM
