No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)

Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.

Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.

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.

Questions 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 META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser 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.

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- Majority of bots aren't allowed to participate here.

Instance A does not federate with Instance B. But B federates with A. What does it mean to a user? (fedia.io)

I've tried searching for other posts that ask a similar question, but I couldn't fine one that could fully make me understand what it would mean in this scenario.

So far from my understanding is that if I browse All, the instance I'm on won't show anything at all from the instances that it blocked. But manually doing the workaround would still show me the community and whatever posts that got federated in my instance. Is my understanding correct?

The other topic of federation that I'm interested to understand as a user are below.

The example: fedia.io states in their federation list that it does not federate with ani.social. But ani.social states they federate with fedia.io.

I can go to say !anime@ani.social just fine via fedia.io, although there is some posts that doesn't show. Is this one of the result of this situation?

Additionally, today I did basically try to subscribe to all the same communities/magazines on my lemmy.world (I'm considering to abandon this account), fedia.io and kbin.earth accounts.

Other than the situation above happened to some communities where some post doesn't sync, I've also found some communities that's just inaccessible from either 3 instances.

Is that another result of not being federated?

Thanks in advanced.

It means both instances will see old posts from before one of them defederated.

Now that A is de-federated from B, they both won't see new posts or comments from eachother. In the case of fedia and ani.social, you won't get any new posts from any of their communities or users. If you post on anime@ani.social from fedia, nobody will see that post outside of fedia users, because ani.social isn't seeing it and passing it around to the rest of the fediverse.

You hav basically the right idea, everything stops syncing when one defederates.

[–] Lazycog@sopuli.xyz 6 points 2 days ago (1 children)

Yup. Since fedia.io was federating with ani.social for awhile you've got a "local copy" of ani.social's communities on fedia.io from back when it federated.

So when you post on those communities it's all happening only on fedia.io and you see posts/comments on that community from other fedia.io users. But, for example, I can't see what fedia.io local copy of anime@ani.social looks like from my instance, because my "local copy" is still federating with the actual instance anime community is hosted on (i see new posts and my posts/comments get sent first to ani.social's original community and federates to rest of instances from there).

[–] JayGray91@fedia.io 3 points 2 days ago (2 children)

Thanks. That's a slight shame. I've only been trying out lemmy / threadiverse for just a few days (second attempt. first attempt was back on reddit APIcalypse) and for now I'm liking mbin a bit more than lemmy. fedia.io being the biggest instance, so that's why I registered there first. next biggest mbin instance is a bit less stable.

I suppose it's still early days for me so I can afford to jump around for now to see what instance sticks, and I guess the software as well.

[–] HubertManne@moist.catsweat.com 2 points 1 day ago (2 children)

I went with kbin because I liked the interface better. Im guessing you are also a person who browses on a computer rather than a phone. Unfortunately something happened with earnest so I moved to an mbin instance. There is a third thing sorta in alpha that looks promising and I keep forgetting its name. It might ultimately have a better interface.

[–] JayGray91@fedia.io 1 points 1 day ago (1 children)

I'm kind of am using both on desktop and mobile equally. back when i was active on reddit, I use mobile apps to browse and save comments to later interact and respond more easily on desktop.

the third thing, is it possible it's sublink or something like that?

piefed seems to be the third defacto for now, but you already said that's not what you meant.

[–] HubertManne@moist.catsweat.com 2 points 1 day ago

no its definitely a thing you can sign up to and not a mod in that way. im just not sure if its a unique activity pub implementation like mbin/lemmy or like taking one of those and adding to it. It might even be making changes to activity pub as part of it as there is something I had read in a convo where someone was talking about how communities having to assign something so they get into a particular pool or something.

[–] rhythmisaprancer@moist.catsweat.com 1 points 1 day ago (1 children)

Piefed? It integrates with a variety of federated things but I haven't gotten in too deep. I have a similar path as you.

[–] HubertManne@moist.catsweat.com 2 points 1 day ago

no its either an mbin/lemmy alternative or it might just be mod of it. Its claim to fame was you choose your interests and it sorta autopopulates your subscriptions.

[–] Lazycog@sopuli.xyz 2 points 2 days ago (1 children)

I highly recommend a smaller stable instance. You are less likely to end up between defederation wars.

Initially it will suck because you wont find communities and your feed will look empty since you need to have atleast one account from your instance subscribing to a community to federate it to your instance, but once you find communities and subscribe you'll have the widest access to content since federation is on by default and instances explicitly choose who they defederate (or they use lists of known bad-instances, but small ones are often not on these).

But that's just my opinion, look into options a bit!

[–] JayGray91@fedia.io 3 points 2 days ago (1 children)

Noted. It does feel like I do have to go look for "the one" instance like that. Sucks as a lurker; that's my default mode lol.

[–] Lazycog@sopuli.xyz 2 points 2 days ago (1 children)

I know how you feel! I myself was a lurker on reddit and I've instance-/software-hopped on fediverse few times until I found my favourite instance+software.

It takes more time and effort, but I'm definitely happier here than on reddit. Fediverse has it's difficulties but it feels more "organic", atleast until now.

[–] JayGray91@fedia.io 2 points 2 days ago (1 children)

It's interesting though, and somewhat nostalgic. It feels like how I was pruning my reddit subscriptions and all. Or twitter. Or other social media. Idk how go through the noise by not pruning what they follow.

[–] Lazycog@sopuli.xyz 2 points 1 day ago

Definitely. I love lemmy more now that I have pretty nice curated /subscribed feed. I hardly ever actually look at /all.

[–] JayGray91@fedia.io 3 points 2 days ago (1 children)

Hmm, I see. This is interesting. It gives me the feeling that I either would "have to" have a generalist account on the least defederated instance to have as wide a net (kind of my early times on reddit), or I would have specialized accounts to specific topics in multiple instances.

[–] HubertManne@moist.catsweat.com 2 points 1 day ago (1 children)

for myself I look to have an account on an instance that federates everywhere. I block stuff myself. Given that I find domain blocking does not work correctly and the language filter is iffy. Im hoping those get improved but the language might be local configs that are not correct or something.

[–] JayGray91@fedia.io 1 points 1 day ago (1 children)

I'd love that. I still need to go looking for an instance that I can fit in and just block and curate myself.

How is the moist instance? is it stable and relatively quick? I'm partial to stay with mbin instances more than Lemmy but I'm still open to anything really.

[–] HubertManne@moist.catsweat.com 2 points 1 day ago

so I chose it because I liked what the guy (originalucifer) had to say about it. Its a single person so I mean I think the main thing is you might have to be ready for it to be over at some point and might have to start again at another fed instance. Not trying to diss but I think this is a reality for any of the fediverse but the smaller the thing the more likely. Its great actually because its part of its strength to me. somethig could fall but its super unlikely all of it will. So if you want to do the way I decided read:

[–] originalucifer@moist.catsweat.com 6 points 2 days ago (2 children)

is there any particular reason ani.social is defederated? just curious

[–] JayGray91@fedia.io 5 points 2 days ago

Sorry, I wouldn't know. I'm new and slowly dipping into lemmy and eventually other parts of fediverse. I'm curious too, but idk if I should ask fedia.io's admin about it.

[–] shani66@ani.social 1 points 1 day ago* (last edited 1 day ago)

The lemmy devs added it to some big block list with verifiable lies as the justification (some same lolicon epidemic). Haven't checked to see if it's still there, but it's a pretty good red flag to watch for bad instances imo.

Probably boils down to Western chauvinism over anime.

[–] Rentlar@lemmy.ca 3 points 2 days ago* (last edited 2 days ago)

Instance A defederating B or vice versa is the same result. Any posts on any inaccessible remote communities will remain and act like local only communities, specific to your instance.
