that’s pretty boring.

well at least we can enjoy their content without their limitations, since we see it from a different instance.

they defederated?

there is an app for mobile. that also offer continuous backup of photos (like gphoto)

if they have the same hash the deduplication thing will work. if they are different quality or other stuff no. thare are plans to implement something regarding more advanced deduplication but not anything implemented at the moment.

it does not matter the instance where you create your profile or community, all are federated. small instaces run better because lemmy is (not yet) good at scaling.

this is so damn useful

immich!

no idea, you should search issues on github.

Anyway comments are replicated across all instances, so nobody stops someone from running a modified instance that does not abide to the comment deletion request. Same for posts, idk about images.

you should consider everything that get published public forever.

there is comment edit history, even if you edit them the original will still be visible
