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.

Why YSK: your upvotes (favorites) and downvotes( reduces) are public information.

If you are browsing through https://kbin.social/ or whatever just click on "more" then activity.

There you'll see info like boosts, reduces (downvotes), and favorites (upvotes?)

Works with all instances for lemmy or kbin material

Anyone can stand up their own instance, subscribe to remote communities, and start receiving all the data necessary to show those communities. That includes posts, comments, and votes too.

Every instance operator is in control of a database containing all the activity for communities that instance's users are subscribed to. They can do whatever they like with that data. That's a consequence of how federation works.

The protocol as it stands today is also generally vulnerable to any malicious instance. A malicious Lemmy server could emit spam, send out bogus votes, or alter its users' comments after the fact (ahem, spez) and disseminate the modified versions. The main tool that other instances have to deal with a malicious instance is ... yup, defederating.

Ultimately, other federated services in Internet history have adopted different ways to deal with this problem:

  • IRC doesn't have a single federation; it has many federations ("IRC networks"), and server operators form peering relationships with one another based on mutual trust and agreement to uphold various rules. A given chat channel only exists on a single IRC network; you can't reach Libera.chat's #linux from a DALnet server. And occasionally a federation completely blows up — see e.g. the 2021 collapse of the Freenode network due to admin abuse.
  • Usenet pretty much floundered on spam mitigation because well-behaved servers didn't eject the malicious and ill-maintained ones.
  • Email has dozens or hundreds of different ways of dealing with bad instances (i.e. mail servers that emit spam), including published blocklists of known offenders' IP addresses. But even then, major mail servers depend on all manner of filters (including ML classifiers these days!) on top of straight IP blocking.
