Lemmy Defederation Sync (LDS) to keep your block list up to date

Hi all, I'm a Lemmy FOSS app contributor that's made a couple of tools for people starting small instances including Lemmy Community Seeder (LCS) for building content on new server's All Feeds and Lemmy Post Purger (LPP) for clearing old posts on smaller instances.
Today I'm releasing Lemmy Defederation Sync (LDS). When launching a new Lemmy instance, administrators may not understand the necessity of defederation with problem instances. Using LDS, you can sync your instance's "blocked instance" list with that of another server(s) whose admins you trust.
Shared Fediblocks are a plague. Get added to one by somebody that personally dislikes you and every instance that uses the block will unknowingly block you.
The issue is there's no oversight here, or at the very least, no oversight that we can trust to be impartial.
When parties form a federation, it's usually with a signed agreement, to maintain the integrity of the federation and keep it together. Shared standards, rules, ideals, regulations, etc. All I'm seeing here are parties trying to carve out a sub-federation, and with no neutral oversight, it's just going to become a "people like me" circle.
And I guarantee at some point people are going to start thinking "Hey, if this instance isn't subscribing to the shared blocklist, that must mean they want those other instances around, and therefore they deserve to be added to the list"
Then just like that, the fediverse has a defacto authority. Instead of one sepz, we have a council of them from the largest instances.
And I guarantee at some point people are going to start thinking “Hey, if this instance isn’t subscribing to the shared blocklist, that must mean they want those other instances around, and therefore they deserve to be added to the list”
Already is happening on the Mastodon/Pleroma side of the Fediverse. Instances getting de-federated because they dared allowed their users to see posts from "bad" instances
This is a terrible idea that steers lemmy into being an echo chamber. Let admins use their own judgement.
But isn't that what this program does? It allows you to choose an instance with admins that you trust. And those who want to review every single one manually can still do that. I'd love this tool. The ones setting up these servers aren't stupid. They can use their judgement and use this tool if they want!
This sounds a bit like how to bring the shared blocklists from Twitter to Lemmy. Those were a disaster on Twitter, and I don't expect it'll end any better here either...
Please don't use tools like this. Manually curate instances you feel the need to defederate with. The Fediverse was built on a model not unlike that of email. You wouldn't just randomly block whole email providers willy-nilly, so you shouldn't do so here on the Fediverse either.
As a sysadmin that's a terrible analogy:
- Shared email Blocklists are the norm, not the exception
- As a professional IT admin I would absolutely blackhole any vile hives of scum and villainy rather than dealing with their BS. If someone is going to do that for me I'll use the tool.
Also a sysadmin.
> Shared email Blocklists are the norm, not the exception
Shared blocklists in IT are managed by industry professionals for the purpose of safety from malicious activity and there are vetted processes for being removed from days lists. False positives happen, but you aren't hung out to dry if you get hit, you just go through the process and clear your name.
Most of this "Fediblock" nonsense is several orders of magnitude less reliable, and filled with toxic people pursing personal grudges. There's no process to clear your name, and I've personally watched multiple admins and their entire communities be publicly mocked and told they "don't owe you anything" for merely asking why they were blocked, let alone how to remedy the situation.
These are not remotely equivalent and anybody who trusts them is a fool. The Fediverse has a serious problem with vile, bitter people who would not be out of place running an HOA. If we are going to emulate the blocklists common in IT, we need professionals in charge of it, not nosy busybodies.
Read my other reply, I'm not talking about email blocklists, my reference is to email providers doing that, which is extremely rare and done with explicit intent and good reason.
Secondly, while I won't disagree there's some vile content out there on the Fediverse, do you trust someone else to make that decision for you? Why would you let someone else decide what is and isn't vile for you and those using your instance? Better yet, how would you feel if some popular instance decides you were the vile one, and because it was a common instance to use for blocking references, your instance is now cut off from a good chunk of the Fediverse?
This is exactly the sort of nonsense that swept Twitter with shared Blocklists, and the potential for negative impact on the Fediverse is even worse from it. Don't let others decide make decisions for you just because it's easy, as it doesn't absolve you of responsibility when something goes wrong.
Admins can and do use email server block lists, though, so maybe that's a great example.
I suppose you're right--for now. But at some point Lemmy etc will grow large enough to make manual blocking infeasible. Just how much effort does it take to start a new instance even today?
Wrong comparison. It's not like a server admin using an email block lists (which are also often implemented badly, as anyone with a protonmail account knows...). It's more like if Protonmail suddenly blocked Tutanota, or if Gmail blocked MS Exchange. The uproar and rage from that would be unceasing.
The Fediverse operates on a model like that of email, and in the email world blocking whole email servers from each other is very rare, and usually done with the most explicit of intent and for a very good reason. That's how the Fediverse should operate as well.
Thank you. I recently set up my own instance and realized the need for tools that can assist in managing.
For reasons an other commenter has said, I think things like fediseer are a better solution to this. The way they use for measuring trust is distributed, like Lemmy itself (just fewer instances, because it is not for use directly by thousands of users, but for admins who are fewer).

That sounds interesting!
and Lemmy Post Purger (LPP) for clearing old posts on smaller instances.
Does that permanently delete posts? Why would you do that?

Reduce the footprint of the install. Text posts and comments are negligible but pictures chew through storage.
And does this only delete visual media by default? If not, this is worse than anything reddit has done ever. I frequently save posts and links to myself in the form of links, for later processing. This would mean that by the time I get to it (can easily be years, honestly), it will have disappeared forever.
Also, if anyone is interested about fediseer, there are useful resources in this post: https://lemmy.dbzer0.com/post/220288
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !fediseer@lemmy.dbzer0.com
Nice to see history repeating itself I guess.
Interesting experiment though. I'd like to see how this plays out.
Disgusting. Let's defederate with everyone whose ideology my echo chamber disagrees with111!
And here all I can think is “latter-day saints”
I see where this can be useful, but is this list categorized or at least indicate why a certain instance was added?
It's different blocking an instance for simply repeated toxic behavior vs political leanings. Sometimes an instance can have both.
Letting new admins know and select categories/tags to block or let through could be an improvement, if it isn't there already:
- NSFW (sometimes people want a SFW site, like browsing at work)
- NSFL (porn might be okay but not everyone have fond memories of ogrish.com and likes)
- Illegal in X jurisdiction (e.g. CSAM)
- Far right or far left
- Repeated instances of troll / spam bot accounts
- Abandoned by admin
There is no way to specify reasonings for defederation in lemmy right now :(
