YSK - for all the things that can make your life easier!
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
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.
For further explanation, clarification and feedback about this rule, you may follow this link.
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.
Rule 10- The majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.
Rule 11- Posts must actually be true: Disiniformation, trolling, and being misleading will not be tolerated. Repeated or egregious attempts will earn you a ban. This also applies to filing reports: If you continually file false reports YOU WILL BE BANNED! We can see who reports what, and shenanigans will not be tolerated.
If you file a report, include what specific rule is being violated and how.

MODERATORS
?
If you're an instance admin, for any post, you can just click "view votes" and see everything tied to usernames, even outside your own instance. Moderators can too, but it's restricted to the communities they moderate.
So if a bad actor wanted to get aces to vote data, they could setup and instance and have it federate with any instance they want to extract voting data from?
Yes, it's very simple too. You don't even need to extract anything from a database or do some complicated stuff. As an admin you have free access to all moderation tools no matter where the post is from, including the option to "view votes".
The IP address thing is not real, though
Just choose a nickname that is random word+4 random digits and don't reuse it on other services
This is the way. Randomise your usernames and use a password manager to keep track of them.
Sir, this is the Fediverse.
It is nowhere explicitly made clear to users that voting is public. It should be made clear if it is going to be
Why would it need to be made clear? Likes on Facebook are public, nowhere does it say "liking this photo will alert every friend you have that you just liked your stepdaughters' friends' bikini pic from 2 years ago."
I like the public vote system. Anonymous systems have a much greater potential for abuse.
Accounts are easy enough to make that you can just burn your account every few months if you're that worried.
It's the other way around here: Everything is public except where it's made clear that it won't be (e.g. email address, password).
For what it's worth, your instance of choice is particularly negligent in regard to informing its users. Compare lemmy.today/legal to lemmy.world/legal, or their respective signup pages for examples. There's little that Lemmy itself or the community at large can do about that 😞
Are you sure about that? Reddit is a fucking cesspool.
In combination with your IP, this is a massive privacy (maybe even physical security) risk. Also, people can target you for your votes.
No.
It would be unusual to be able to exactly identify someone purely from their IP, but let's say someone posted from their work IP in a small company. It would substantially lower the bar to dox them.
Let's go further and ponder if an authoritarian regime setup an admin and started coorelating dissent ip's collected from user when they did things like paying parking fines, or signing their online tax forms.
Let's say that they collected all that and trained an LLM on it, then when you go to get a passport renewed or are stopped for a traffic violation and ask the LLM if you're a dangerous person based on their criteria.
It's not a direct problem, but it has slippery slope all over it.
Seems like a good thing to me. Should be a better known feature.
How would I go about seeing this information for myself?
Yeah, at worst it’s a necessary evil to prevent a rogue user on a second instance from mass downvoting. Your username is tied to your vote, because otherwise a rogue user could just spam downvotes at whatever they didn’t like.
Instance 1 has a post. Instance 2 has a user who disagrees with that post. User is able to spam downvotes, because instance 2 is not binding their username to the vote. So Instance 1 has no way of knowing if the votes are multiple different users, or all one user. The only real solution here is to disable external voting, but the entire point of the fediverse is cross-compatibility and self-hosting. By binding the username to the vote, instance 1 is able to detect repeat votes and disregard them.
this is why i vote at random, like two-face doing his quarter thing
You get 3 accounts. Say you want to upvote something. You downvote in 1 account (randomly selected), upvote on another, and upvote on the third. So it’s net +1 and the only way to see how you voted is to piece together all 3 of your accounts voting history. Need more privacy? No problem, just use 5 accounts instead of 3.
/s
wait, so what do i do with the first shell again?
I did this last night putting my son to bed, said heads you go to bed, tails we stay up. Jokes on him though, double heads. And he fell for it, what a sucker. Hope it works when he's not four, or I at least don't need to do it.
you're raising a future supervillain
Russia really should just leave Ukraine, though. (Sorry, I just saw the context for this a few minutes ago and can't help myself).

I like piefed because it lets you see at a glance if someone is a serial downvoter. On each piefed user profile is a thing called “attitude” and it’s a ratio of your upvotes vs downvotes. ~~100% means the person doesn’t downvote people. 50% means they downvote and upvote equally. 0% is only downvotes.~~ Edit: I saw someone today with negative % so it must be 100% is all upvotes. 0% is half upvotes half downvotes. -100% is all downvotes.
It shows up for people outside piefed too so i see you too lemmy angry people.
oh no. I should upvote more. I'm really bat about voting at all 😓
I would never downvote cereal.
Unless it was grape nuts. That shit is like eating gravel.

Why are you saying IP addresses are publicly shown here and why is (almost) no one correcting you? That would've been an enormous privacy risk that would've required intentionally fucking users over. Just doesn't even make sense to write what you did about IP addresses. Seems like you're just hoping to cause some panic.

Why is public voting a massive privacy and physical threat but public posting and commenting is not?

If you ever get banned for the way you vote then abandon that reddit space.
What do you mean by Reddit space?
Many subreddits ban you for interacting with subreddits they don't like for personal reasons.
If the same thing happens here it's our duty as users to abandon that space

I remember learning about this and not giving a fuck. I vote stuff on occasion, but generally don't vote or care about the votes on my comment.

An entire thread of people missing the point 🙄
I have to assume it was the same case on Reddit, except it was only info available privately, to whomever. Now, every psychopath and their mother can find people who disagree quietly and hunt them down!
