I've seen this "deletion is not guaranteed on lemmy" warning shouted loudly and often by a few individuals over the past month or two, mostly on reddit. It makes no sense in context, because deletion is not guaranteed on reddit, either. Or on any other public forum.
For the record, lemmy devs addressed it in a discussion here.
I'm starting to think it's propaganda sponsored by reddit, hoping to scare people out of leaving.
Just to add more information or context to your answer, this site exists, so instead of people arguing about "Lemmy sucks on privacy" or "This place is a hell hole for anonymity", maybe people should rethink about what they're going to write.
Agreed with everything you said. The anti-Lemmy posts over there are starting to smell like astroturf. Although who knows, a lot of it follows similar anti-Mastodon posts I've also read there, so either some people really dislike federated social media that much or Twitter astroturfers were busy on Reddit after the blue bird was "stunned" by Elon.
Reddit is required by EU law to delete all of your data if you ask them to (and you're an EU citizen). I suspect it's much harder to do on the fediverse, though in theory they're subjected to the same law.
Point 2 is true but frankly I don't see the issue, you'll see that a person wrote a message they deleted, no exploitable information has been leaked, and if the account is ever deleted even that gets deleted too
Point 3 is outright false, the moment something is deleted, ActivityPub spreads a delete command to anything federating it
As an aside, the politics of the Lemmy creators are still mentioned a lot, but at this point the tankie population has been pretty much utterly outnumbered due to the Reddit migration, Lemmy has grown from a few hundred people to thousands and is STILL growing, hopefully it's no longer an issue.
Hey, you wanna give more context to point 3? I only found comments regarding that delete will spread but the servers can (though should not I guess) just replace the deleted object with a "Tombstone" object and thus not really delete.
I'm busy right now, will look for the exact code snippets later, but in summary from what i read earlier when i first came across these claims last month or so, any activity that happens with a comment is also federated: Creation, editing and deletion, so barring any cache that will eventually expire, or an instance going down, the lifetime of a message will be replicated across anything that federates with it.
And yes, a patched instance could just ignore deletion and save everything, but at that point you're fighting a rogue element and the rules change, we're discussing the normal, designed behavior of the software.
This has been discussed several times before and it's still as incorrect as it was originally. The author of that post has both a severe misunderstanding of how federation works, and a severe beef with the developers of Lemmy over their political differences.
So, obviously an anti Lemmy bias there, and not entirely true, but there are some aspects of federation it can be dangerous to ignore.
There is a different primary privacy focus here, and it provides an extreme level of privacy but places an extreme level of responsibility on the user for their own privacy, more than most places.
There is a distinction to a potential scrape and a system designed to duplicate, often irreversibly at submit.
There are also other things people are often not aware of and the community is not doing a great job communicating. Admins are not doing a great job of protecting themselves either.
For instance many, still don't know votes here are entirely public.
If you understand this all and are comfortable, great. Many do not prepare themselves and would engage differently if they had a better understanding.
Holy fuck. I'm glad I never heard of or went to Raddle until now. The comments in that thread, including mod comments, are CANCER. There's one guy who repeatedly tries to correct their falsehoods, but he just gets belittled and called a liar. Fuck that shit.
It's more of the same tankies vs. anarchists fighting you see in a lot of leftist spaces, if I were to guess, and the Raddle set doesn't notice that not all Lemmy instances are tankie ones by a long shot.
I certainly don't like the Raddle community's reaction to this, however Beehaw's community has shown somewhat similar reactions to certain topics that have come up. Having some reactionary drama seems unavoidable in any social group. That said, the software that Raddle runs on is pretty sleek. Seems to rival Tildes in quality for a link aggregation and forum software. But it's inability to federate makes it fundamentally different from lemmy.
It's ironic that the anarchist devs created a centralized aggregator in Postmill, while the tankie devs who initially made Lemmy, made it a part of the fediverse. I'd honestly expect it to go the other way around.
You might want to put a note about the sensationalist title, so that people don't just read the headline and come away with the wrong idea.
There's really no other way to implement this sort of a network. Once someone federates your messages, they can disconnect their server and keep your message forever. It doesn't matter what sort of protocol you put in to try to "securely redact" messages after the fact, there is still an edge case that the information that you make publicly available is available for eternity. If not by Lemmy itself, then by web scrapers, search engines, archives etc.
Cycle through generic accounts and don't put PII up. That's the best you can do with this sort of social media. If you want more privacy you need to take it to a non-public space, like chat rooms.
Until they add a history feature for edits (i'd really appreciate that, actually. I edit my shit all the time just to fix errors, but i know there's plenty who use the feature maliciously to change how an argument sounded)
And you're dreaming if you think reddit can't get whatever you "overwrote" back.
Concur on the edit history feature / log. I'd also support an optional "rollback and lock edits" feature for mods so bad actors couldn't just edit to seed discord.
I'd support a delete feature for posts, but people do need to understand that content released into the fediverse is out there for good, more or less.
