Edit: obligatory explanation (thanks mods for squaring me away)...

What you see via the UI isn't "all that exists". Unlike Reddit, where everything is a black box, there are a lot more eyeballs who can see "under the hood". Any instance admin, proper or rogue, gets a ton of information that users won't normally see. The attached example demonstrates that while users will only see upvote/downvote tallies, admins can see who actually performed those actions.

Edit: To clarify, not just YOUR instance admin gets this info. This is ANY instance admin across the Fediverse.

Out of curiosity, is there a particular set of circumstances where knowing how you voted on certain posts a bad thing? I would imagine that if you didn't want people to know you're voting/looking at specific posts, then you either don't vote/look at the posts, or you set yourself up an alt account on a different server. But let's be honest, if you'd be embarrassed by something you're looking at, maybe you shouldn't be looking at it. Just my 2¢.

If I understand it right, due to the federated nature where each server has to sync with other servers, any admin from any instance (that is not defederated) can read this data. Which may be a pretty big problem from Lemmy. One of the main selling points is that you're on instances where you are not the product, but it looks like that all an advertising company that collects and sells user data for profit needs is to just quietly set up an innocent looking Lemmy instance for quarter of a cost, and just get call the data served to them from all other servers. For free.

That's actually way worse that just giving your data to one company that sells it later, because you at least know who has it.

I don't know what's the extent of data that are shared between instances, but I think you can create a pretty good picture of someone from their upvotes

I'm sure that someone will dox themselves, then somewhere else mention where they work. Post on some gonewild pages (is that a thing here) and then make a poorly worded opinion on a sensitive subject and lose their job. Of course Internet hygiene is important and you shouldn't dox yourself but after several years you'll slip up and these things will bite you .

Cue tactical voting, virtue signalling and influencing. By having them anonymous you don't have to worry about those things. There's a reason voting on a political party or candidate is anonymous, and voting on opinions and posts should be so too.

Does it only log usernames, or does it record ip addresses as well? I am much more okay with one than the other.

[-] lieuwex@discuss.tchncs.de 21 points 1 year ago

Only your instance admin can see your IP.

[-] jerkface@lemmy.ca 24 points 1 year ago

Holy shit. HOLY SHIT.

I just realized what this actually MEANS.

It means that when you like or dislike something so much that you unvote and then vote a second time, people can tell. This will change karma forever.

The things I upvote and downvote are in line with my personal values and I am not ashamed of that. I have no issues with anyone knowing my reaction to a post. On Discord anyone can see who leaves reactions on a message. Same with Facebook. It will show you who added what reaction.

What does this mean for admins regarding GDPR? Is lemmy still not GDPR complient? Are there options in place if users request their data?

An issue has already been raised: https://github.com/LemmyNet/lemmy-ui/issues/1347

That said, don't just call people out who downvote you. No one owes you an explanation if they thought your post was bad. I've already seen it once and it was pretty childish.

So if one downvotes something and then removes that vote, does doing that removes it saying they downvoted or does it still keep it on record?

[-] muddybulldog@mylemmy.win 21 points 1 year ago* (last edited 1 year ago)

I had to run an experiment on this one.

It appears that changing you vote causes the old vote to be completely deleted from the database and a new vote cast and propagated.

Edit: The above description is what happens in the COMMENT_LIKE or POST_LIKE table HOWEVER the ACTIVITY table reflects both actions, which makes sense since it's a complete transaction log. So, it's a slightly more complex query but the history is maintained.

Fully expected to be buried since I'm late to the party.

That's really only half of it, there is no real erasure possible when everyone's holding a cached copy. Personally... I kind of like it, I don't hold any value to the words I contribute here as long as they're for everyone.

But everything and everyone is living in concentric glass houses here.

If you are doing anything tgat could get you in legal trouble on the internet, only use acounts that can not be linked to your real life identity, and always use tools like Tor. Do not depend on tools like private messages, private voting, etc. In those cases, there is always someone who can give you away, and service admins will give out information when the feds come knocking.

I only downvote awful/hateful comments so I usually stand by what I strike down. I can understand why this may concern others though.
