You can't delete any text in comments or posts either - or at least not reliably, as any federated instance could choose to ignore deletions.

You should basically consider what you write or post here public, and probably public for good. But here's the thing - same goes for the entire rest of the Internet as well, basically.

[-] Enkers@sh.itjust.works 128 points 8 months ago

You should generally think similarly about anything you post anywhere on the internet that has open access. If it's viewable anonymously, anyone could save and mirror it.

The only difference is it's almost guaranteed on a federated platform.

[-] deweydecibel@lemmy.world 32 points 8 months ago

I feel like, after over a decade of smartphones and snapchat and such, a younger generation needs to be thought better what putting content on the Internet means on a fundamental level, and those of us old enough to remember the more open web need to be reminded.

If you don't want everyone to see it, and I mean everyone, then you shouldn't put it online. For all intents and purposes, once you hit send, it's now a part of the internet. You might get lucky and be able to remove it, but that's the exception, not the rule.

If that’s the case then I need to say this: “Penis ass butt cock fart”

[-] ooli@lemmy.world 25 points 8 months ago

I didnt know about that. This is a bit scary to be honest, and the first time I feel a bit taken aback with lemmy

[-] Spotlight7573@lemmy.world 62 points 8 months ago* (last edited 8 months ago)

You also know that all votes are technically public and can be viewed by any instance admin that's federated with the server a community is on, right? There's no way to see that in the Lemmy UI at the moment but the data is there on the server.

[-] JohnEdwa@sopuli.xyz 24 points 8 months ago

The votes are directly visible from Kbin for users as well.

Actually, they're adding it into the UI for admins. And they're letting mods see to.

https://github.com/LemmyNet/lemmy-ui/issues/2320

Rather than do anything to try and protect this data or obfuscate it in any way, they just decided "fuck it".

And that's frankly worrying. I truly don't think people understand why Reddit didn't let mods see that information. The avenues for abuse here are innumerable.

I mean you could say the same thing about reddit - anyone could scrape reddit and save comments and stuff, even if you later delete them.

If someone can see something on their computer, they can save it and you won't be able to take it away. I mean... it's just how the internet works.

That's pretty much how everything on the Internet works, FYI. Lemmy is just upfront about it

[-] bdonvr@thelemmy.club 23 points 8 months ago

The deletion should federate across almost all instances, but there's no guarantee and also someone will almost certainly one day set up an archive server that just listens to all activity on Lemmy like uneddit used to be for reddit.

And seemingly nothing is actually deleted, just hidden. Boost for Lemmy currently has an interesting bug where any comment, deleted or removed, can still be seen by simply selecting "copy post text" from the menu, as the API will return what was previously there.

PSA, if you want to delete a comment or post, be absolutely sure you first edit it to be blank.

Welcome to the hell of being a lemmy admin. There's a reason why lemmy admins are fed up with the developers.

[-] gabe@literature.cafe 111 points 8 months ago

For context, there's a lot that goes on behind the scenes when it comes to lemmy admin stuff especially in the matrix channels. There is a significant frustration and lack of confidence in the lemmy developers at this point. Even those who try to contribute to the project get eventually feeling pushed out.

[-] HobbitFoot@thelemmy.club 49 points 8 months ago

Based on what I've seen on the public facing part of the developer side, I get the feeling this isn't the kind of group that can build the kind of organization required to make this sustainable in the long run.

I'm just waiting for when Beehaw releases that they've given up on Lemmy and have created a new tech stack.

[-] Serinus@lemmy.world 62 points 8 months ago

It's open source. We don't have to depend on the original developers.

If it gets too bad, someone can just make a fork.

Afaik people are just impatient with the developers and have different short term goals.

In terms of new tech stack currently theres sublinks being made by devs/admins of a bunch of instances (discuss.online, lemmy.world, programming.dev, etc.)

That sucks. As a 3rd party Lemmy app developer, I've only had positive interactions with the Lemmy devs. They're even being proactive in communications.

Not sure I understand. How could there possibly be a solution? Isn't this an inherent problem with federation? You can't un-share information

So what have they been doing to nuke the csam images, editing the database directly?

[-] Ghostalmedia@lemmy.world 65 points 8 months ago

Often just nuking all image uploads made during a certain time period. Which is why old image threads in Lemmy have time periods littered with broken images.

[-] QuaternionsRock@lemmy.world 21 points 8 months ago

I don’t understand why Lemmy needs to have a built-in image server at all. Reddit didn’t have one for the longest time and it was fine. Sure, I don’t think anyone would be particularly happy with going back to Imgur etc., but it doesn’t seem worth the trouble.

[-] Draconic_NEO@lemmy.world 19 points 8 months ago

Often they delete all images during the time frame of a CSAM attack, as that has been the only real feasible way to ensure images weren't left behind. Though I think a few images have started using AI detection methods to remove images like that automatically (read up on that here and here), also Pict-rs now has a Log linking uploaded images to the user, so now images can be purged with the users.

How exactly does Lemmy remain in compliance with laws regarding, for example, a user's right to have all data associated with their account deleted (right to erasure, etc), or ensure that it is only kept for a time period reasonable while the user is actively using your services (data protection retention periods, etc)?

It's not a big deal for me, just strange to think Lemmy of all places would be built to be so anti user's data rights. The user is ultimately the one that decides what is done with their information/property, after all.

[-] viking@infosec.pub 44 points 8 months ago

Lemmy is not a singular software or website, every instance on its own need to ensure compliance with their respective laws where they are domiciled.

But if instance A is domiciled in the EU, and the content mirrored to instance B in Zimbabwe, where no right to be forgotten exists, then a user of instance A can't invoke any laws beyond what the local admin can control.

That's amazing for high availability of content - it's essentially mirrored in perpetuity - but a nightmare for privacy advocates. AFAIK there haven't been any court cases related to deletion requests, so that's still virgin territory.

What exactly is a KYC selfie? Is it a photo of an ID card? I figured out WUI is WebUI. The author uses some strange acronyms I never heard before.

It's very American that they can steal your identity with just one photo. My European state issued ID has data on both sides, so if someone would take a photo of it won't be enough for anything. Also if you loose it you just get a new one and noone can use the old one for anything.

[-] Rentlar@lemmy.ca 35 points 8 months ago

KYC is Business/Finance lingo - "Know Your Client".

Yeah the fact that exposing one number/piece of information puts you at risk to a significant amount of other information about you being exposed is peak USA.

Dear aussie.zone users,

I can delete photos. Just give me the url of the photo you need killed and I'll happily delete it for you. But also, don't (accidentally) upload a nude.

I hate to use it, but this is why I still find imgur useful. It works.

Some stuff on Lemmy just doesn’t have a robust feature set yet. Especially around content moderation.

[-] sjmarf@sh.itjust.works 33 points 8 months ago* (last edited 8 months ago)

I’m a developer of a Lemmy client. When you upload an image to a Lemmy instance, the instance returns a “delete token”. Later, you can ask the instance to delete the image attached to the delete token. So as long as you keep hold of the delete token for a specific image, you’re able to delete it later.

Lemmy-ui (the official frontend) will give you the option to delete an image again shortly after uploading it. However, it’s not possible to remove the image after actually creating the post, as the delete token associated with that post isn’t remembered anywhere on the Lemmy backend.

As for other Lemmy clients, YMMV. The client I work on (Mlem) deletes images if you remove them from a post before posting it, but has the same pitfall as Lemmy-ui in that it won’t delete the image if you’ve already created the post.

It would be possible to locally save the delete tokens of every image you upload, so that you can request that they be removed later. I don’t know of any clients that can do this yet, though (if someone knows of one, feel free to mention it).

Edit: clarity

This got me curious on how many images are on all Lemmy instances combined and how much storage it all takes up.

[-] Shadow@lemmy.ca 52 points 8 months ago

I can tell you that for lemmy.ca we use 778gb

[-] Fudoshin@feddit.uk 22 points 8 months ago

Holy fucking shit balls. I contemplated seeing up an instance on a £5 VPS. Hmmmm, I think my scale is a bit off.

[-] Shadow@lemmy.ca 24 points 8 months ago

If it's just a private instance, your storage needs will be way less. We use object storage, so it's actually pretty cheap (like $5-10 a month iirc). We're not storing that all on the server disk.

You can consider almost anything publicly posted to Lemmy as permanent. As I keep saying, please be careful.

I do think a way to automatically store the uploaded image urls and associated delete keys under your user is a necessary feature.

For personal image hosting I use postimage, but any external host that lets you modify/remove images under your account will do.

What happens when you share a link to an image? Does Lemmy just save the link or does it make a copy of the image?
