Hey folks! Just realized something that makes Lemmy different from Reddit. Because of the federation, your votes are not technically anonymous on Lemmy. At least, I think.
Although there’s no UI to look at a user’s voting history yet, one could conceivably be built by an instance. Perhaps coincidentally, I hear there’s instances out there populated by mostly bots?
I think this issue is overblown. Instances of Lemmy might run modified code and choose to save things that the user intended to delete, of course, but the default setup of Lemmy seems reasonable to me in terms of how it treats deletion.
Currently it keeps deleted posts forever to allow users to un-delete if they choose, but deleting your account clears everything. And I believe there’s work in progress to discard deleted posts after 30 days. Details here: https://github.com/LemmyNet/lemmy/issues/2977
