Interesting difference from Reddit: Upvotes/Downvotes are not anonymous (programming.dev)

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?

Is that ID local to the instance or universal across the fediverse?

Thanks to Marius, looks like when you interact with a server you get assigned a local id that's tied to your username/email combo. So no global ID but all your actions on a server are tied to you. It wouldn't take a lot to link that to your account on your home server.

Overall idk if it's a big deal. Upvotes and such need to have a user ID tied to them in order to keep things straight. Unless someone wants to update the Lemmy software to start encrypting the GUID on the table an instance owner will always be able to see what you've voted on ON THEIR instance. Reddit totally can as well, but they had a reason not to put their users on blast (At least until lately lol).

It'd take some collusion to put that all together across the fediverse.

I dunno, this is as far as I chased it. It should give you a starting point to dig further if you choose... but I don't plan to at the moment.

As far as I know (another assumption haha), there’s no universal IDs across the fediverse.
