The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rule 1- All posts must begin with YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:
**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.

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: Obligatory RIP my inbox.
Well of course. The instance stores all data in a postgres database. How else will it be able to remember anything?
Maybe this is not obvious to non-programmers but you never see everything in the user interface for any system. There are tons of records needed for the system to track everything that goes on.
Since posts are federated, they will exist in the local db as well as on each instance.
It's not that it stores data, it's what data it stores. Your votes construct a very detailed profile that doesn't mean anything to another human but an AI can read it like a very simple book. They don't necessarily need to be so strongly associated with your account thanks to simple technology like hashing.
If you're a programmer, you'd know there are ways to authenticate a transaction without giving away giving aways, or storing, the person who initiated the transaction. It's more difficult to do of course. So it's often not done.
Sure but what danger lies in that? Users are not using their real identities here so they are semi-anonymous.
That's not always the case. My username has heritage dating back all the way through to Slashdot, Digg and through Reddit. While you may not know me that doesn't mean I'm unknown or anonymous.
On Reddit I could upvote or downvote as I pleased, without exposing my POV on controversial topics to the general populace. Only commenting would actually out me. That's not the case with Lemmy and making people aware of that is a good thing, imo.
But it's the fact that it's so easy to reverse engineer. You can take that data to build a large profile on each user in your instance (or possibly all instances)
Sure, this can be abused. Build profiles on each user based on what they are talking about and what communities they subscribe to. Then start sending them direct Lemmy messages with ads or links to shitty or dangerous sites.
The fact that anyone can start an instance and get all this info sent to them is a bit unsettling. But we will have to find a way to protect against it.
That's why the topic is "You Should Know" rather than "I've Had A Revelation That No One Has Ever Considered".
And it doesn't mean it's nefarious. It just means... you should know.
Ok... have to admit that I miss one thing from Reddit... I have no awards to give.
