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

[-] paholg@lemm.ee 19 points 2 years ago

But you can delete your copy, ask others nicely to delete theirs, and refuse to accept more copies of the same thing.

I'm not sure if Lemmy supports any of this, but it seems pretty important for e.g. child porn.

How can you refuse to accept more copies of the same thing, when you deleted all the version it can compare itself to?

[-] asdfasdfasdf@lemmy.world 11 points 2 years ago

When you get a deletion request, hash the bytes and store the hash.

[-] Antergo@lemmy.ml 9 points 2 years ago

There could be a legally binding contract stating that any deletion request must be forwarded to all parties it was send to, and that upon receiving such a request the data must be deleted. I do not think this would be unreasonable to ask to servers, especially as this deletion receipt could be fully automated.

Or there could be a delay of one minute before posts get federated, giving the user the option to quickly delete a comment or post.

[-] maltfield@lemmy.ca 1 points 2 years ago

That’s a great idea :) Maybe you can submit a feature request for this on GitHub?

[-] SorteKanin@feddit.dk 2 points 2 years ago

legally binding contract

Maybe, but consider that federated servers may be located in entirely different legal jurisdictions, so this might be hard to create, let alone enforce.

[-] perviouslyiner@lemmy.world 1 points 2 years ago

When writing a contract you can just specify which legal system the parties agree to use - this is quite common.

[-] Antergo@lemmy.ml 1 points 2 years ago

I don't think it will ever come to a lawsuit, nobody would ever want that. Under the GDPR you must be able to delete content, and the server must communicate this to all federated servers. So in effect, there is already a legally binding agreement between all servers that this deletion request must be honored (for people physically in the eu), it's just not.

lemmy servers are already breaking the GDPR if they don't follow forwarded deletion requests from people in the eu. This would just effectively be an extension of this to data from all people.

The images aren't federated afaik. They live on your home instance. If somebody else views them, they're loaded directly from there.

However there's no link between the images and your account. You can't delete them yourself because Lemmy doesn't store the "delete token". They're effectively orphaned.

[-] SorteKanin@feddit.dk 2 points 2 years ago

Not true, images are federated. Sometimes they are not copied if your instance has a lower image size limit than the instance the image came from (if the image is too large), but generally images are copied between instances.

[-] Blackmist@feddit.uk 2 points 2 years ago

I did check a few embedded images, and they still seemed to be served from the original. So I dunno. Maybe they're copied and still served from the original, which would be an odd thing to do.

[-] SorteKanin@feddit.dk 2 points 2 years ago

Aah the embedded ones in comments? Yes to my knowledge those aren't federated. But pictures posted as posts will be federated.
