Great post, but here are some questions those graphics raise, that I couldn't find an answer to, and which have only my experience with email, usenet and irc for reference (all of which are federated, easy to abuse, had a host of problems, and have slowly migrated to centralized versions to solve these issues):

• how do you ban someone?
• what stops him from spinning 100 amazon ecc instances, federating 100 servers and spamming his thing 100 times from 100 different instances?
• how do you even block an instance?
• what happens with the federated content once the source instance goes down?
• say lemmy.ml and memes goes down, how do you post a new reply in memes@lemmy.ml? does it even work?
• i haven't found any info for syncing accounts across instances (to prevent this loss) or if this is even possible at low level
• what happens with comments and pictures once a federated instance goes down? say, if i selfhost and i crash without backups, does my content and posts disappear?
• can i pull it back?
• what kind of capacity planning would I need to selfhost say, a decade worth of reddit browsing? assuming I only care about my posts and what I save, would they be accessible for me?

Uhh... What happens when I do create the same username + email on several servers?

Hello, thank you for the post,

This clears up a few things for me, because the concept of Fediverse are still "abstract" for me.

When i first join, I created multiple accounts on lemmy.world, beehaw, lemmy.ml, because i thinks its mini Reddit, with its own content, and its own account.

Now i know that i only need one account, and i can still see the post from another instances.

There's still some questions that i can't understand

1. The decentralized nature of the Fediverse, how does one search or now what community on another instances?

2. Say when in Reddit, we have /r/aww for example, it means that lemmy, beehaw, or another instances can have their own /c/aww ? does it means that we have multiple instances of /c/aww or, we have one single /c/aww but distributed between multiple instances

Sorry for the bad English :D

Thanks for the easily visualiser, needed something to explain it to friends.

Might be a dumb question and not sure how to ask this but.. If I spin up my own instance, what happens with my posts if I decide to tear down the instance? Like, will the delete get propagated to other instances where I may have commented?

Thanks, I was so confused with everything but this answers a lot of questions.

This is really great! I've also been quite lost but am enjoying the learning process!

One thing I've just learned is that all the different instances don't neccessarily 'federate' with each other in real time (there can be some lag in content showing up in your instance) or at all. Only instances your instance federates with sync up? I think? :-) I see beehaw.org have had to cut ties to a couple of instances to help with the flood of new users and content happening right now. It seems while you can still view their content from your instance you can't comment or post to it? I think? :-)

Another useful definition that comes up is "Federation". As I understand it's referring to the whole set of mini-Reddits for example, and multiple Federations exist in the Fediverse, correct me if I'm wrong.

You rock!! As soon as I find a way to pin this I will.

Awesome post. Cleared things up so much for me

I saw a post yesterday about it, and someone said it was a known issue.

I'm more concerned about how the votes on this post are bouncing up and down between 4 and 818 as I'm typing this reply. Seems like there are some problems here...

EDIT: WOAH this ended up under totally the wrong post. Odd bug...

Good infographics! It is better to change the screenshots to light theme (instead of dark) since the links and buttons are hard to read in the photo.

This is helpful! Does anyone know what it means when you try to subscribe to a community and it just says "Subscribe Pending"? That has happened to me 2-3 times, and it just seems to stay like that.

Right now i've had an issue myself where the potential answer to my issue is in a privated subreddit. So, i had to search even more. Frankly, it highlights the downside of having this become a thing. So i am on the fence whether i want that to happen at all.
