Why do deleted OPs and comments keep showing up on other instances like lemmy.ml? (feddit.nl)

You can find various of my OPs and comments, but I deleted them days ago on the feddit.nl instance. These OPs aren't visible on the feddit.nl instance, but they're visible on lemmy.world.

Why? The same goes for lemmy.ml, but it concerns a different number of OPs and comments.

Yes, posts can remain on some rogue servers forever.

Up until recently, deleted posts were stored in all server’s databases forever, just with a deleted flag next to them. It was recently changed to purge after 30 days. Even so, someone could setup a server that ignores all deletes and will still retain them forever.

For privacy, editing your post first may be useful as that seems to propagate faster. This could still suffer from the same rogue server issue not respecting edits.

This is a problem that doesn’t seem to have an answer yet.

Worth noting that it's not a lemmy specific issue. There's Reddit databases out there with full edit and delete history.

If it's publicly visible at any point, one should assume it's on the Internet forever.
