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.

I recently learned that voting on lemmy is not anonymous. Anyone can get information about who has upvoted and downvoted a post or comment.

In combination with your IP, this is a massive privacy (maybe even physical security) risk. Also, people can target you for your votes.

Sadly, this is something where I would prefer Reddit over Lemmy. Big tech scrapes data from both places anyways, at least Reddit is safe.

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

[–] Azzu@lemmy.dbzer0.com 79 points 4 days ago* (last edited 4 days ago) (19 children)

Would be my question as well. It seems quite obvious that if you participate in publicly viewable discussion, that the stuff you do is publicly viewable.

If you don't want it associated to your physical person, use a VPN and unidentifiable account name.

(And the statement "at least reddit is safe" seems absolutely ridiculous to me.)

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.

Don't tell anyone, but your posts and comments are also public.

[–] BoosBeau@lemmy.world 14 points 4 days ago (2 children)

Only you can see this comment Daniskarma. The Leering League of Lemmy SEES you Daniskarma and we have taken notice. Cease your efforts to spread information about public posts and comments, or ELSE Daniskarma. We're watching you.

While it is important to know that voting is not private (nor truly is direct messaging), that is not in itself a danger.

Lemmy is community driven, and so it is — broadly speaking — governed by community norms and the platform is responsive to the needs of those norms. If someone is harassing or mistreating you on the basis of your voting, then you can take it up with an admin. I've seen people called out for the use of vote manipulation, but I'm not sure what it would look like to be targeted based on your votes.

By the way, there are also mechanisms for publicly addressing grievances with mods and admins.

Most importantly, recognize that it does take time to adjust to the reality that no one cares about the fake internet points here. Reddit uses dark patterns to manipulate users into equating votes with worthiness. Having a lot of karma on reddit contributes to a person's reputation and credibility there. Here, no one cares, or even sees, a person's vote totals. Like most everything else, it's technically public, but it's not visible or indicated.

Why does reddit want you to care about your karma? For engagement and metrics. If people are only incentivized to share genuine interests and human interaction, then they won't scroll mindlessly for quite as long. If every post and comment is incentivized for maximum virality, then Reddit can sell more eyeballs to advertisers. Plus, if people care enough about their fake points, they will literally pay to buy reputation. Reddit doesn't care about your well-being, just your ad impressions. Like any other social media corp.

Welcome to a better, healthier, more transparent place. We are far from perfect, but no one here will use dark patterns to mine you for content.

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.

I would never downvote cereal.

Unless it was grape nuts. That shit is like eating gravel.

Russia really should just leave Ukraine, though. (Sorry, I just saw the context for this a few minutes ago and can't help myself).

Lmao, what!? Reddit tries their best to know exactly who you are, where you live, your education, where you work, etc... And then they sell that data to anyone.

I don’t think IP addresses federate? I think only your instance admin can see your IP address. In any case, though, you should generally always assume that your up/down votes on any service are recorded and tied to your username. If you can come back later and change your vote, that vote is tied to your username. It may not be visible to other users, but the server admins can absolutely see what you’re doing.

Reddit might not make your votes publicly visible, but they’re absolutely tracking them and using that information to select what you see, including advertising. They might not directly share those votes with advertisers, but they almost certainly are sharing your interests based on your votes. And you should assume Reddit and others will comply if the government comes asking for what users liked a post the government opposes, or who downvoted a post praising a new government initiative.

It depends on your threat model, but your threat model might change. Freedom of speech might be curtailed by politicians even when that’s supposed to be unconstitutional. What might be safe to do online now might become unsafe in a year or two.

YSK: every action you take online, even as simple as an Upvote or Like, might be recorded and may come back to haunt you

It's the nature of the beast. Federated software holds no secrets.

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

[–] disobey2623@lemmy.dbzer0.com 18 points 3 days ago

This is the way. Randomise your usernames and use a password manager to keep track of them.

[–] HeyThisIsntTheYMCA@lemmy.world 25 points 4 days ago

My votes are a massive privacy risk? How? I'm putting them out there publicly willingly. As is the nature of the internet.

[–] bdonvr@thelemmy.club 25 points 4 days ago (3 children)

In combination with your IP, this is a massive privacy (maybe even physical security) risk.

Your IP would only be seen by your instance (which is inevitable, you gotta connect to it after all). But there's no way for anyone else to look up your IP.

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.

A lot of people here still refuse to understand that Lemmy, as it currently exists, is a privacy nightmare, and the voting thing is just the top of the iceberg. There are several de-anonymization attacks possible involving dynamically serving different content to different users. This, combined with the public voting makes it possible that someone can dox an account and expose a lot more information than other forums where that information is more private.

Public votes also open the fediverse up to much worse astroturfing IMO. It's incredible feedback for bots and trolls to see exactly who is interacting with their posts and comments. It's frustrating that a bunch of people here have convinced themselves of the opposite, and insist that public voting is the only way to combat brigades and trolls, which is an incredibly shortsighted stance which doesn't scale nearly as well as it does in the other direction.

I dsiagree that transparent upvotes are an issue. In fact i think it's a powerful feature for community to self correct and resist astro turfing.

On reddit votes have become meaningless because they are not 1 person == 1 vote and its completely astroturfed. You can literally got to buyredditvotes dot com (not real but real ones are very close just google it) and stuff any post with votes and nobody will ever know.

Transparent interactions are key for community health even if behind anonymous nicknames. So all interactions should be transparent.

My only issue is that many lemmy instances are blocking popular VPN services which is very dangerous. I understand the bot argument but (even though residential proxies are dirt cheap these days) user safety suffers hard here.

I’ll downvote everyone here if I damn well please it!!!

[–] A_norny_mousse@feddit.org 16 points 4 days ago* (last edited 3 days ago) (2 children)

It was something I had to learn, coming from Reddit.

But I made my peace with it. Let the mods* see my up/downvotes. If that becomes a problem then, well, the Lemmyverse isn't right for me.

* I was told that anyone can see this, with a little effort.
But I have not heard about this applying to IPs.
Obviously someone running an instance (an admin, not a mod) can see who visits that instance; that's just how servers work, and it's valid for reddit as well. If you can't live with that you must use Tor or VPN.

So while I agree that everyone should be aware that up/downvotes + username are visible to anyone, I'm not sure about the IP argument.

Seems like a good thing to me. Should be a better known feature.

How would I go about seeing this information for myself?
