This is the reason:
Looks like the PieFed's old post deletion does not take into account whether a poster is local to a deleting instance or external to it.
At least one banger of mine on this comm is already affected.
Memes on piefed.zip should be safe.
It is off by default. Admins can set the content retention policy on any community.
On piefed.social I've set pretty much every meme, shitpost and anime community to expire after one year or less. Check the sidebar of the community to see, it's beneath the moderator list.
Good to know. Is that only in the local sidebar or does the retention policy federate with the community info?
I'm not super active in meme communities, but would be nice to know they're on a ticking clock before I do post something. That, or I just avoid Piefed communities.
All piefed.social communities have infinite retention. Our stuff is high quality and worth keeping forever, it's just the trashy Lemmy content that gets deleted ;-)
