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.

MODERATORS
 

They changed the algorithm on Dec 7, 2016.

Before: https://web.archive.org/web/20161206000344/https://www.reddit.com/

After: https://web.archive.org/web/20161208000333/https://www.reddit.com/

Best guess, based off the vote count differences of those two days, is that if you see a vote with 100,000 count, it's likely closer to 20,000 count (divide by roughly 5 or so).

There was a post about it by KeyserSosa on Dec 6, so it's not some conspiracy or anything.

I figured YSK.

"Completely" made up is a bit hyperbole. They're not random, they are usually in some way indicative of the number of upvotes/downvotes a post is getting.

The reality is that any naive upvote system can be gamed. The more popular Lemmy gets, the more lucrative it will be to systematically manipulate which posts/comments are promoted and which get buried. And a naive voting system that just reflects the raw number of up/down votes is trivial to manipulate. It's harder than a signal in the noise issue, it's more of a signal in a deliberately crafted manipulated signal issue.

If Lemmy gets more popular, it's only a matter of time before it's forced to come up with alternative methods for deriving post sentiment.
