My home instance is shutting down soon.
https://lemm.ee/post/65824884.
I am slightly unclear about what the instance admin meant.
Because of how Lemmy is built, everything posted on lemm.ee will still be accessible from other instances, even after we go offline.
How are other Lemmy instance able to access the content from the post-shutdown lemm.ee?
Do all the other Lemmy instances keep a copy of the content from lemm.ee?
If so, wouldn’t that be rather taxing on each Lemmy instance? (since they have to keep a copy of all the content from all instances they federate with).
I tried reading this up by researching on Lemmy federation, but this is still unclear to me.
Note that because of the way federation works, the domain can be bought by someone else who can then use the connections and links to lemm.ee images and posts to peddle spam and other nonsense. It’s not a problem as long as the domain name stays under control of the lemm.ee admins, but if they don’t renew their registration then anyone can pretend to be the old lemm.ee server.
Best for lemm.ee users to delete images from their posts and comments now so whoever grabs the domain in a year or so can’t use it to inject weird shit into your old posts as easily. Of course they still can create new accounts for all.the old account names and post in your name if they want, but the user private keys should prevent that for individual posts if the other server software is smart enough to validate them.
I didn’t know that. That seems to be a very bad decision.
I would have thought there was some sort of private public key involved in instance authentication.
While they could put up weird images, they can’t change posts without everyones private keys.
