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?

I don't quite follow this. It might be a slow query with a full scan, but you could select on user-id, join post-ids with community-ids, and aggregate how a user votes in various communities, or do an export that joins votes and posts to analyze for word-clusters they up/down or whatever.

I think they mean you couldn't exclusively pre-aggregate it to a vote tally on the post record and not track it per user. It must be tracked on a per-user per-post basis (in some way).

Ah fair. Assuming you have DB access to do this at all, you ignore the post-ids or join them to other tables to do all kinds of stuff.
