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.

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.

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.

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.

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

[–] 13igTyme@lemmy.world 10 points 2 days ago (1 children)

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.

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.

If you ever get banned for the way you vote then abandon that reddit space.
