My best guess is that the humans want to hide useful information to be more like "AI", therefore honouring their future overlords. /s
It means once a post is 366 days old it gets deleted.
Are you sure this isn't a piefed thing?
Either way it's an incredibly bad idea, lots of old posts being indexed by search engines will help Lemmy grow. The one thing Reddit has is over a decade of archived posts that answer even the stupidest question.
It really depends on the community. If the community is mostly discussion based help, it's a bad thing to delete it.
If it's a community of spongebob memes, it's less of an issue to delete old posts.
PieFed dev Rimu answered at https://piefed.social/comment/12376368:
The posts in that community will be deleted after that many days. For remote communities this only affects the local copy of each post and the post will still exist on the source instance and other instances (unless they too delete their copies). For local communities the deletion federates so the post is removed everywhere.
PieFed is intended to run for decades and storage costs money so admins can set how long they want to retain content for, on a per-community basis. It’s up to them to decide what is worth keeping forever and what should be trimmed.
AFAIK piefed.social has ‘forever’ for the retention of all local communities and only trims remote communities. In some communities piefed.social only keeps posts for very short periods, like 28 days, because it’s the kind of content people look at once and has no lasting value beyond that.

IMO that's not for admins or mods to decide. That's for users and (eventually) historians et al. to decide, and it's only knowable in retrospect, if ever.
Hell, most of archaeology is digging through literal trash.
Nope, the one who pays the bills decides. If you disagree that's fine. You are free to host your own instance, where the users can decide how much space they want to take up for saving old pictures.
They can decide if they want to pay for it, but they can't decide whether other people think it has value or not.
Ah gotcha, now I understand what you mean exactly and I agree.

Exactly, which is what I want to see with the Fediverse. Could be a PieFed thing yes.
It's the first option on your list.
Not everything is worth keeping.
Admins can configure this on a per community basis.
Awww man...I mean its kind of a good idea, but on reddit I've had people reply to 10 year old posts.
Its a weirdly nice feeling.
But I do think we're in a data hoarding mentality and wish to preserve everything. I think it is important to let things go.
Edit: Though on the flipside, I do appreciate especially on technical posts, to go back and look up people's answers/solutions to questions I have.
Even if the answer is no longer valid, perhaps the person who provided the answer can offer an alternate solution.
reddit posts were read-only if they were older than a few months until pretty recently
That might have been true for some subreddits, but not all.
I've had people reply on pretty obscure subreddits years ago, on posts that were years old.
my 'pretty recently' is anything in this decade

In general I'd agree, but I'd like to see a Web where search engines show more answers on the Fediverse/Lemmy instead of Reddit. If the default is removal after 365 days, this won't happen.
Without a specific example, everyone else is left guessing, same as you, but I'd read that as the first option. If it's a lot of communities, I'd guess it might be the policy of the server they are hosted on.

A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
Reminder: The terms of service apply here too.
