For me its having a single instance that indexes all the communites to which all other instances can then pull that information from so when I go searching for communities the I’ll have access to every single one with needing to post the entire URL in the search bar
Software engineer here. Historically we started not hard-deleting anything because sometimes software does bad things and we never want to accidentally delete anything that could be important since then the only way to undo it is to restore the database from a backup. So it’s better/safer to literally not allow the application to ever delete anything from the database.
That being said, I could see an option in ActivityPub to delete comments, but with the distributed nature of Lemmy you would have to trust every server you federate with to listed to the protocol and delete the comments too since they are stored on the other servers as well.
Trust of federated servers isn’t the issue. We already trust federated servers to publish the text we wrote and not some alternative version the owner wanted us to say.
The problem is instance owners don’t even have the option to obey deletion requests. They want to help delete your content but they cannot.
The whole “what’s the point of building it if there’s a possibility one dude doesn’t obey the request” is whataboutism.
I’m not saying we shouldn’t be able to hard delete comments, I’m just explaining why the Lemmy developers might not have started with hard-deleting comments. I agree with you we should have the option and it should propagate regardless of any instance settings.
My point in mentioning other servers not deleting your comments is that ActivityPub is an open standard. Technically someone can write a Lemmy competitor that federates with your instance and does not implement the hard deletion of comments. It’s allowable under the protocol. That doesn’t mean the feature isn’t worth implementing, it just means there are caveats to “this comment disappears off the Internet forever” like we’d like.
I fully understand wanting to restore things from a backup, but I don’t grasp how giving us the option to hard delete our own posts and comments would interfere with that in any way. Safest? Perhaps. A reasonable tradeoff for such safety? Not in my opinion.
As for your latter point, maybe that’s one of the drawbacks to federation that does not get discussed enough. However, I’d think there’d be some sort of solution to put more control of our data into the hands of the users.
