Thinking of moving to sh.itjust.works from lemmy.world - one question about the rules though... - Lemmy.world

If I post nsfw onto a community hosted on lemmynsfw, for example, from the sh.itjust.works account, would that breaking the no pron rule, or not necessarily, since it’s posted on a different instance?

No, it doesn’t break the rule IMO. Yes, the image is hosted on sh.itjust.works, but it’s not posted ik any community on sh.itjust.works, so… it should be OK.
Of you post to an outside community, is not hosted on your insurance. It’s hosted where it’s posted.

I don’t think that is actually true…

OK let’s make a test. I have 2 accounts on sh.itjust.works, this is my lemmy.fmhy.ml account. I’ll attach a pic, see where the link points to.

The link says lemmy.fmhy.ml 🤷.

The potential liability for instance owners due to this is massive. Images should be stored in the instances of the community they’re posted to.
It’s fundamental to the design of Lemmy’s implementation of federation via ActivityPub that all content from an account be hosted on the account’s instance.
If it’s an ActivityPub feature, this is somewhat of a poor design if you ask me (or at least not being able to change this). He’s right, this feature could put instamce owners in legal problems, because the data in question is actually stored on their server, not the server that you posted the image on.

Yeah, you’re right… but I think the problem is, the login info… but, than again, how could it store copies of my post, but not images.

In any case, I do agree that this is something that should be looked into and discussed.

I don’t see why the login info is an issue, and storing a copy of a post wirh just a link to an image makes sense.
I really have no idea how other instances actually confirm that you’re posting from another instance, not just emulating that you’re a poster on another instance. That might be a part of ActivityPub, but I haven’t looked at code, wouldn’t know.
This is part of the ActivityPub protocol, but I haven’t looked into it enough to know how it’s defined.
Indeed, this is a huge design flaw. You would basically have to police everything that users post on other instances as well. Do you even have moderation tools for this?

Huh. Well that just makes no sense structurally. Thanks for pointing it out though.

How does this thing work at all? You would expect it to all be hosted to the site the community is hosted on. So now when a comment thread is fetched, it has to go to all these other servers for every single comment from another instance. This is actually mind-boggling.

Does anyone have an ELI5 for why it’s done this way?

Actually, the post content is saved on the instance where the post is posted as well. That post is called a copy, the original resides on the poster’s originating instance. But, not the media, no, that resides on the instance where the poster resgistered.

Some Lemmy Technical Questions - Lemmy.World

Yes, I’m certain I could final answers to all these questions via research, but I’m coming here as part of the Reddit diaspora. My guess is that there’s a benefit to others like me to have this discussion. I can vaguely understand the federation concept, the idea that my account is hosted at an individual Lemmy server and that other servers trust that one to validate my account. What’s the network flow like? I’m posting this to the lemmy.ml [http://lemmy.ml] /asklemmy community, but I’m composing it on the sh.itjust.works interface. I’m assuming sh.itjust.works hands this over to lemmy.ml [http://lemmy.ml]. How does my browsing work? Is all of my traffic routed through sh.itjust.works? Assuming there’s a mass influx of redditors, what does it look like as things fail? I’m assuming some servers can keep up under the load and some can’t. If sh.itjust.works goes down under the load, can I still browse other servers? Or, do those servers think I should have some token from sh.itjust.works, because my cookies say I’m still logged in, and I can’t even do that? Are there easy mechanisms to allow me to grab my post history? I’m assuming most (all?) Lemmy servers are hosted in home labs? The idea of Lemmy excites me, but the growth pain that could be coming scares me. Anybody using a CDN in front of their servers? That could be good, but with unconstrained growth, that could be costly, which is very bad. I can imagine lots of different worse case scenarios, but I’m curious what those of you who run servers imagine for the best case scenario? A manageable growth that just gets more vibrant communities, which can’t ever lead to the breadth and variety of Reddit? Also, for those running servers, have any of you experienced issues during this growth? What scares you?

Basically everything goes through your instance. If you make a post, it goes to the copy of the community that’s on your instance. Likewise if you comment. If you join a community, your instance starts listening for changes and stores those on the instance.

That way if another instance goes down, you still have a copy of all of the content there that someone on your instance is interested in. So that way pretty much everything is backed up.

I personally think we can do better, but it’s an easy enough system that all but guarantees that content doesn’t disappear. You could even set up an instance that never deletes anything if you want to make sure you don’t lose any data.
