Interesting difference from Reddit: Upvotes/Downvotes are not anonymous

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?

In term of privacy this is pretty bad though. From the upvotes/downvotes activity you can very easily build a whole graph of stuff you like/dislike. For advertisers that's juicy data.

Good for those advertisers. Too bad we don't have ads.

Or upvote/downvote randomly, or, on a lot of stuff so the interest pool is huge. I'm upvote stuff I see just to participate and give the poster a "someone seen this post" feel good high.
