What’s stopping Reddit from just nuking it and deleting all the posts in one day?
Considering the current state of affairs, if Reddit nuked all posts they’d restore them in a day or two lol
Money and rules around said money. Reddit might not be profitable but it’s still a business. They have a team of people who’s job is to make sure the business continues. Spez can do a lot of stuff but he’d have a rebellion if he tried to press the off button. And he’d have a lot of debts.

Short answer – nothing.
Longer answer – Those communities, posts and comments will still exist on the other servers, but sadly interacting with them will not federate that data to other instances anymore, since the host instance is no longer active.
So you would still be able to see the posts and their comments on other servers?
Yep, but if you reply to said post, only other users on YOUR instance will see those comments. Any other instance and it would be like you didn’t reply at all.
OK thanks. I am still a bit confused at how it works tho, if they did nuke the website, where would the data from the post and comments be stored
So trying to not go into the technical details too much but when two instances federate with each other, they literally share all of the community, post and comment data with all other federated servers. But it’s the job of the host do manage that passing of data.
Now once the host decides to go offline, that activity of informing all other instances of “hey here’s something new about XYZ community!” no longer happens, but each instance still has the historical data from prior to them going offline. So you can still see that old data and still technically reply to it. Just that the host won’t tell other instances that you did reply.
Replying to my own post with an example…
Lets assume you have an account on Lemmy.world. Let’s also assume you see some post on Lemmy.ml. And finally lets assume you have a friend that’s actually on Mastodon. When you reply to that post on Lemmy.ml, Lemmy.world sends your reply to Lemmy.ml and then Lemmy.ml tells Mastodon (and all other federated instances) about your reply. But if Lemmy.ml decides to go offline, Lemmy.world has no where to send that reply to, so it’s only kept locally on Lemmy.world. The user on Mastodon can’t see it as their instance wasn’t told about it from Lemmy.ml as it went offline.
So lets say lemmy.world and then lets take beehaw.org (I know they are defederated lets assume they are not) for example. All the posts and comments which are hosted by lemmy.world on hard drives or servers, are also hosted by beehaw.org and vice versa? So the amount of data is actually doubled in size?
Yep. Add in a 3rd instance and now you have 3 copies of the database, essentially. It’s just that each instance is responsible about telling the fediverse when updates occur to communities on their instance.
If the fediverse gets really big, lets say the size of reddit, it may be hard for all the different instances to store all that data on their servers
We got to see exactly what would happen a week ago when Beehaw defederated from lemmyworld. For us (on lemmyworld) it was like if that server had disappeared. Comments from beehaw stayed on the list, but new content from them (comments or posts) didnt show.
Damn that sucks
But the host can initiate a request to delete the data from other federated instances. This will be handled automatically unless the other instances specifically block/stop the deletion request.
Am I right?
In theory ya, an admin could remove/delete the communities, posts and/or comments and then let that data federate out, and they would then be hidden on all of the other servers. But there’d be nothing stopping someone from still replying or creating new posts while that’s going on.
I could be wrong but I don’t think there’s a mass delete tool for the admins.
What’s stopping someone from scraping lemmy.world and creating another archive site?
Not a stupid question ehh!
literally nothing.
I mean that’s every web site all the time though. The owner/admin can always just delete it.
Nothing, but all other instances would still exist. While it would suck, you can just make a quick hop to a new instance (or host your own if you’re worried about who runs things) and you’re back up and running.
Compared to if something like Reddit were to be deleted, nothing would exist.
There may be a need for a service that backs up a user’s instance content for future migration to another instance.
What’s stopping that one person from pooping? That’s the real fucking question.
Opioids maybe
For 3 whole days nonetheless!
You’re not supposed to ask. You’re not supposed to ask goddammit.
Like others have said, nothing is stopping them. That is why it is important to spread communities around to other reputable instances, so if something like that does happen, only the communities on that particular instance are lost.
What’s stopping you from burning your house down?
The answer is usually not that the house is completely impervious to fire, nor even that the fire department would come and put it out, but that you don’t want to do that.
Nothing is stopping me from burning my house down but what if the person who hosted this website / instance doesn’t want to pay to host all the data anymore or manage it (or is that not how it works)
Burning my house down will cost me money. Shutting lemmy.world down will save the owner a lot of money. They’re not really comparable.
The reality is that a lot of lemmy hosts will rise and fall over the years, and a lot of communities will disappear with them.
Someone finally implementing full replication / migration / domain virtualisation, that will. atm, there are other things more pressing for the dev team, though. (Anyone here who could fund such major development?)
Btw. i think more likely than big instances being abandoned by their owners (instead of transferring to a new owner), is them being taken down by some law enforcement or legal procedure. Liability costs can make any not-for-profit endeavour vulnerable to bad big player attack.Nothing.
Likelihood of that actually happening: Incredibly low. Lemmy world is built with being the general server for a lot of people in mind. There’s a big admin team. It’s a higher likelihood for a random one who finds they can’t afford to run a instance.
lemmy.world didn’t even exist last month. It’s funded by patreon. https://blog.mastodon.world/welcome-lemmy-world
Nothing. The admins giveth and the admins taketh away.
