freamon

I’d be wary of getting a conversation node from anybody other than the original author (as described in the second approach).

There’s a reason why, if you want to resolve a missing post in Lemmy, etc, you have to use the fedi-link to retrieve it from its source, not just from any other instance that has a copy (because, like the “context owner”, they could be lying).

For Group-based apps, conversation backfill is mostly an issue for new instances, who might have a community’s posts (from its outbox), but will be missing old comments. Comments can be automatically and recursively retrieved when they are replied to or upvoted by a remote actor, but fetching from the source (as you arguably should do) is complicated by instances closing (there’s still loads of comments from feddit.de and kbin.social out there - it will be much worse when lemm.ee disappears). So perhaps Lemmy could also benefit from post authors being considered the trusted owner of any comments they receive.

PieFed is just a Fediverse platform that aims to inter-op with Lemmy in much the same way that it aims to inter-op with any other Group-based platform (MBIN, PeerTube, NodeBB, Wordpress).

Lemmy’s “quirks” are the reason why your account won’t see Polls from MBIN, or channels from PeerTube, or posts from NodeBB, or backfilled content from Wordpress.

It’s not my intent to criticise Lemmy, but these are verifiable problems, whereas it doesn’t seem fair to criticise PieFed for problems that you can’t clearly remember.
