in general, on the fediverse assume that nothing you delete will actually be deleted. once your post/comment is viewed on another instance and thus copied over to that instance, it's possible that whatever you tried to delete will just stay on another instance until that instance vanishes.

You can undelete comments, so I’m guessing “hiding”
deleted by mod still shows in the modlog so probably no security concerns there. deleted by user stuff should really not be returned but its possible (ugh) that they're just doing that on the frontend. but deleted comments are definitely not removed from the db. Account deletion used to and might still overwrite the content of all your comments in addition to marking them deleted

They definitely are, I can read deleted comments on boost.
Ya I went into old threads to test and found comments which were apparently deleted about a year ago still available.
Used to be able to click source in jerboa and others to show deleted comments.
I still can on boost.
I don't know when we stopped teaching this concept. When I started using the Internet some 30 years ago, there was a broad understanding that once something has been published, it can never be truly deleted. The individual was expected to know this, and avoid publishing information they might want to conceal.
That's not just for Lemmy or the fediverse, but for everything on the internet. When you "delete" a Reddit post, Facebook post, X-cretion, or any other published content, it remains available to anyone who had a copy of it, as well as anyone with access to the service's data. Including any cloud provider they might use, and whatever backups they might make.
True "deletion" is only possible on a machine that you fully control, and only if you deliberately render that content unrecoverable. Anything less is just "hiding" it away. Hiding it away may be "good enough" for practical purposes, but there is a significant difference between true deletion and what a service provider calls deletion.
With Lemmy, the original you upload to your own instance is copied to every other federated instance. There are provisions for your instance to inform other instances that you would like that comment deleted. But, there is no enforcement mechanism. They can't be digitally compelled to remove your content. They can ignore that deletion request; they can even use that deletion request to flag your content for blackmail purposes, if they want to.
Privacy laws like the GDPR can provide a legal obligation to delete your data, much in the same way that a speed limit sign can provide a legal obligation to drive less than 35mph. A legal obligation to delete is obeyed about as much as a legal obligation to not harass people about their car's extended warranty.
I and most other people understand this.
It doesn't mean websites can't do their best to help their users out.
No reason to make things easier for an adversary.
I feel like I'm here talking about treating municipal drinking water and you just wrote a long post explaining that not all diseases are transmissible via water. 30 years ago everyone knew that you can get the flu or cancer or eczema no matter how clean the water is..... But all this eternal September riff raff thinks if you just clean the tap water all other problems magically vanish. Sigh.
If you understood that concept, you would have had the answer to your question before you asked.
oh sweetie you didn't understand the question.
