Introduction

As far as I know, the software used by Fediverse, a decentralized social networking site, makes information public due to its decentralized nature, and as a result, it's often possible to obtain feeds of the latest information via RSS.

However, the extent to which this is possible varies depending on the software's capabilities and features, and I was interested in the functionality of each piece of software, so I decided to write this article to research and summarize the state of RSS on Fediverse, including its URL structure.

This article is based on a pioneering article titled "Finding Fediverse Feeds" that appeared on the website Hyperborea: Kelson Vibber.

Stream RSS feeds to Your Fediverse Feeds

A well-known method of distributing RSS feeds from the web to ActivityPub is software (server) called RSSParrot, which was created for that purpose.

In addition, in the Japanese-speaking world, there is a public Mastodon instance called the RSSフィードbot鯖, which is dedicated to RSS Bots and is also widely used.

!fediverse@lemmy.world is not a place to file your grievances with "free speech", disrupting users, moderation, etc.

If you have problems with users: File complaints to the mods or just block them.

If you have problems with mods: File complaints with admins of the instance or just migrate to an alternative community.

If you have problems with an entire instance: Just leave it.

As it stands right now, it looks like we have to just judge based off of how old posts are to see if we can still interact with a community.

A big grab bag of news, that ties into the question of 'Where Does Community Live?'

Hello, I'm currently setting up a nodeBB forum with some federated Communities. I wanted to test out how this post will work throughout the other instances. If you would be kind enough to leave a comment to see if it works, I'd appreciate it. :)

[Edit] does anybody know if nodeBB has a way to prevent federated upvotes from contributing to forum member specific reputation points?

It's now way prettier and contains almost 1300 accounts.

You can show/hide columns, there is a powerful custom search and a button to download an CSV with the handles of all visible accounts for import. There's also the language, the country of origin, and a direct link.

Digg's officially launched now for about a month and it's... really underwhelming.

The "Most Dugg" posts by upvotes as of this post:

+110, +107, +89, +86, +84, +84, +79, +79 (roughly in the last 24 hours)

As compared to Lemmy/Piefed/Mbin as seen on Lemmy.world (Top in last 24 hours):

+1.22k, +952, +855, +751, +669, +646, +620, +612

That's really poor from Digg honestly.

Most major platforms still rely on a very old identity model: one username, tied to one email, tied to one permanent account. Once something goes wrong — lost email, deleted account, forgotten recovery info — the identity is gone forever, even if the user wants to return.

Examples many people run into:

Deleted Reddit accounts permanently lock the username, even if the user returns years later.

Facebook accounts can’t be recreated once deleted, and recovery depends entirely on old email/phone access.

Steam accounts are tied to payment methods or emails people may no longer have.

Many services keep usernames in a permanent record even after deletion.

This creates a strange kind of digital permanence: you can delete an account, but you can’t delete the identity attached to it.

So I’m wondering:

Could online identity work without permanent usernames at all?

Could identity be modular or replaceable instead of tied to a single handle?

Would hardware keys, biometrics, or wallet‑stored codes solve the “lost email = lost account forever” problem?

Why do so many platforms treat usernames as permanent even after deletion?

Is this a technical limitation, a policy choice, or just legacy design?

Could federated systems eventually support more flexible identity models?

I’m curious how others think online identity should work, especially in a world where people change emails, lose access, or want to return to a platform without being locked out of their own name forever.

Note:

  • this is related to the fallout and backtracking from Discord's age verification changes
  • I haven't confirmed what license this is being released under

Despite the issues with the companies involved, maybe there is something here that Fediverse platforms can benefit from. Whether it is using the tools directly, or using it for ideas when building something better.

From the site:

Coop provides content review tools and includes the ability to route reviews to the experts, show relevant information for a comprehensive review, and take action. The platform includes built-in integration with the National Center for Missing & Exploited Children’s (NCMEC) API for mandatory reporting of child sexual abuse material (CSAM), ensuring compliance with relevant regulations.

Osprey is an open-source investigation and incident response tool that allows safety teams to understand what is happening on their platforms and take actions at scale. Osprey’s lightweight, user-friendly design makes it especially valuable for platforms of all sizes, from grassroots communities to established platforms that need powerful tools without enterprise-scale infrastructure.

Bluesky is taking from it already:

"We're excited for the implementation and release of Osprey," said Aaron Rodericks, Head of Trust and Safety at Bluesky, which plans to adopt Osprey. "This represents exactly the kind of open collaboration needed to democratize safety tools. By implementing Osprey, we're helping prove that effective safety infrastructure can work for platforms of all sizes, not just those with massive resources."

Important progress has been made regarding bringing MLS end-to-end encryption to the ActivityPub protocol, with developers already building implementations and providing feedback to a future version of the protocol spec.

Idk, it might be old news to everyone.

I just discovered that we can follow the magazines the profiles publish, like !brasil-dw_brasil@flipboard.com that turns into a community, or follow them directly like @dw_brasil@flipboard.com, turning all of their posts into a microblog feed (on mbin, mastodon, etc).

Might be interesting to people, if they want to see some different type of posts, news, articles or cultural analysis.

I see this as a win-win, they get their "someone entered your website through flipboard and the fediverse" (the links come with only this tracking) and we get different "content".

So I decided to set up a nodeBB server on a VPS and am trying to get everything set up - and I am trying to get the fediverse working. I have a couple of questions for anyone who might have some experience.

  1. I am using cloudflare for the domain host, and it seems that I need to turn off bot fighting in order for the federation to work. Is this actually the case, or is there something I am doing wrong? If it is the case, is it that big of a deal? Will I get a lot of spam or bot traffic? Is there a custom rule I can make that night not be as good as bot fighting, but mitigate it slightly? (Without paying for additional cloudflare services) I'm not sure what I'm doing with cloudflare tbh, I've just been asking an LLM to help me correctly set it up.

  2. I think I have it working, but I followed my piefed account within my nodeBB profile to test it - and while my profile shows that I am following the piefed account, the actual indicator that shows number of people following remains at 0. (See photos. On mobile atm, but it's the same on the desktop.)

  3. How does the federation actually work - I'm new to the fediverse, but I'm curious of how to actually use nodeBB with the fediverse. Is /world for people to simply use the forum as a hub to browse their other feeds? Is there also a way to set up each category posting to specific instances? What is the "standard" or "expected" way to integrate the forum into the fediverse - and can it be used to help bring new members to the forum?

Sorry if some of this is trivial, slowly trying to navigate and wrap my head around things. Hopefully someone on here has some experience with this?

Vote manipulation is getting more common. Some recent examples:

While the accounts were banned, the malicious voting activity stuck around.

Should admins have the ability to discard votes, and if so, which admins? Should community mods have that ability? Can you think of any ways that tools like this could be abused?

Hi there! So I understand that federated systems can speak to one another and interact. My question I guess is should I be using my Mastodon account to log into PieFed, and PixelFed, and Bookwyrm? Or do I need to create specific accounts for all these services, just as I did before?

I understand that someone on Mastodon could potentially follow my PixelFed account and see my posts. But wouldn't it make sense to have one single identity (if one wished) so it collected all of my stuff in one place? Just wondering if I am missing the point?

Sorry if I sound like an idiot here. I really love the idea of federated services, just want to make sure I am "doing it right" so to speak.

Hi, new to the fediverse, mainly looking at Lemmy and mastodon right now through mbin, liking it very much.

I'm a Japanese language learner, currently at N3 and wanted to look at some fediverse content in that language. Keep hearing about misskey, but registration is limited from outside of Japan? I'm going over there next month, does that mean I could open an account while I'm there?

Also a bit confused about how it works, when browsing as a guest everything seems to scroll at lightning speed, how is one supposed to use it?

This app could potentially supplant Tik Tok overtime. As Tik Tok's censorship following it's acquisition by US investors such as Oracle, Silver Lake, and Abu Dhabi-based MGX, and UpScrolled already having questionable ethics, this may be the path forward.

Im right now using lemmy/piefed but what other neat projects should i look into as a newcomer to this world?

Im not looking for anything in particular, i just want to expand what i use and see more projects.

evil.social down for weeks

There's a Sharkey-like (Catodon) instance called evil.social. A few months ago, I created an alternate account there so I could have an alternative to calckey.world (another Sharkey-like instance) for situations where Calckey would be experiencing downtime (with Calckey itself having been an alternative for my earlier Friendica account, after Friendica began experiencing frequent downtime occurrences; eventually I ended up staying on Calckey permanently).

At the time, their ActivityPub federation capabilities didn't seem to work properly, I couldn't fetch posts/comments from other instances as well as Calckey.world can. Nonetheless, I still kept the evil.social account as an alternative.

Now, it's been a few weeks since evil.social began returning 502 (Bad Gateway).

Anybody knows what's happening with said instance? Is it temporary downtime or the instance is likely gone forever? If the latter is the case, what alternatives to Calckey.world, other than Evil.social, should I be aware of, as someone who's used both to personal micro-blogging as well as interacting with posts and comments from threadiverse, and someone who's used to write lengthy texts (so max char length matters to me)?

Stupid question, but I thought you click the sidebar, and the three options were "join/leave, post, and block".

But now, the ONE time I want to block a community, I don't see the option. So I go to another community, just to see if it looks different. It doesn't.

The communities now only have join/leave, and post. No block.

Edit: Problem solved for me. Should I leave this post up for any future people who ask this? Or should I delete it so future other people don't try to answer a solved question?
