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. We are not here to ban people who said something you don't like.

If you file a report, include what specific rule is being violated and how.

That is really concerning. Activity Pub should have a mechanism to hide those. If by any chance, one's identity is reviled, their entire behaviour history would be out in the wild. The more one use an account, the more information is getting shared. Social engineering is a real thing.

The only way is it be absolutely private by not interacting (lurkers), which is not good for a social media like Lemmy or by changing accounts often.

No we shouldn't. Anyone can create an instance and scrape whatever data.

Assume that all the posts and comment you make are public and linked to your real identity and don't say things you wouldn't say in person.

It's a pretty simple concept.

Shame, guess I can't say categorising Palestine Action as a terrorist group is dumb.

[–] Croquette@sh.itjust.works 5 points 7 hours ago (1 children)

My comment was misguided because it didn't take the US social context into account.

You can't say it, but I can though.

Categorising Palestine Action as a terrorist group is ultra dumb.

I know that already, I'm fine with what I said.

Oh god this discussion again... We totally haven't had this before:

That is really concerning

The only way is it be absolutely private by not interacting...

I don't know if this is news to you but this is not a lemmy specific problem and basically applies to the entire internet...

identity is reviled [I assume revealed]

The fact that most instances permit external image hosting permits obtaining user IP addresses by posting inline images hosted on a server created by an attacker, then harvesting IPs there. I noticed when going through the code that Lemmy, as of 0.19.4, has an option to protect users of a home instance by proxying images viewed there. However, it requires bandwidth and disk space, and I don't think that many home instances have it on. It is definitely not on on my own home instance, lemmy.today.

0.19.4 release announcement:

Image Proxying

There is a new config option called image_mode which provides a way to proxy external image links through the local instance. This prevents deanonymization attacks where an attacker uploads an image to his own server, embeds it in a Lemmy post and watches the IPs which load the image.

Instead if image_mode is set to ProxyAllImages, image urls are rewritten to be proxied through /api/v3/image_proxy. This can also improve performance and avoid overloading other websites. The setting works by rewriting links in new posts, comments and other places when they are inserted in the database. This means the setting has no effect on posts created before the setting was activated. And after disabling the setting, existing images will continue to be proxied. It should also be considered experimental.

Many thanks to @asonix for adding this functionality to pict-rs v0.5.

I don't know whether PieFed and Mbin presently have comparable functionality.

One major issue is that proxying the images will create more bandwidth usage on a home node, since they're serving up all the images viewed by users of that home node, as well as disk space to store the proxied images


it's more-expensive to run a node in that mode.

Unless your home instance has this option enabled, you should probably consider your IP address to be globally-visible. Note that using a VPN will mean that only the VPN's exit node IP will be visible.

If by any chance, one’s identity is reviled, their entire behaviour history would be out in the wild.

So close to a sweet meter. What do you think of

"If, by some chance, one's handle's reviled / their foul history would be out in the wild."

? It's not perfect. Probably just a little more work-shopping.
