I have been using lemmy for a while now (since Reddit’s API issues) and just recently discovered this website:
Seems I can simply input any user and I get their whole history of upvotes and downvotes, with dates and links. I also tried it with a Piefed user and it worked.
Kind of a deal breaker for me. Don’t feel comfortable even upvoting when these details are public to anyone.
Interesting, I’m also feeling a bit disenfranchised. Why all the downvotes on this post? Wait, let’s check who these evil downvoters are… Yeah case in point, I see the problem here as this could lead to malicious trolling and the start of an undesirable platform.
Edit: lemvotes throws a 404 not found so did the fediverse dodge a bullet?
Simply a wrong URL: https://lemvotes.org/
Anyway, there’s no way to hide the information. The instances need to communicate with each other and send each activity, so if I upvote something, my instance notifies yours (and every other it federates with) about it so that your instance can display it as well.
That’s most likely how the site works - it’s simply an ActivityPub server which gets notifications from every server that federates with it.
Theoretically, your instance admins could defederate from them and then it would stop getting updates.
