If you can create a Lemmy instance and federate, you can shovel data about every vote linked to an account (sh.itjust.works)

I've created this post: https://sh.itjust.works/post/8898162

And some admin showed they can see how the upvotes\downvotes go.

If you are concerned about privacy, you should know, that this data on Lemmy can be easily mined and tracked.

Well, not only this data, all activity on lemmy is public since it needs to be federated (sent to all instances subscribed to the community will receive all activity).
Which means any person can track anyone if they subscribe to the same communities the user's instance has.

AFAIK the only activity not sent is saved content, and downvotes from content hosted in instances which disabled them.

EDIT: for more example, here's my upvote to this post

"actor":"https://lemmy.pe1uca.dev/u/pe1uca","object":"https://sh.itjust.works/post/8931097","type":"Like","id":"https://lemmy.pe1uca.dev/activities/like/f6b0cced-4e1c-41d7-bf11-349b680c4d84","audience":"https://lemmy.one/c/privacyguides"

And here's the original comment

And all instances which are subscribed to this community need to receive this information to keep it updated.

Butt it's not private! /S

All federated data (thus public) should be easily available to the end user. Otherwise we create a false sense of security.

Privacy is not the same as security....not to say Lemmy is either, but it's definitely not "private."

IP addresses of accounts are also private?
