Friends, if you haven't already, it would be a big favour to me if you could enable tags.pub to boost your public tagged posts.

Just search for @_followback in your Mastodon UI. Click the follow button there. (Don't try to follow from the profile page; it doesn't work yet.)

It will follow you back, and when you make a post with a hashtag in it, the server will boost your post from the appropriate hashtag.

#tagspub #hashtags #activitypub

And if you're interested in a hashtag, search for thathashtag at-symbol tags.pub in your Mastodon search UI and follow it there. It will boost all the content it finds with that tag to you.
@evan Oh nice! @janboehm has a yearly live-streamed event with his podcast @festundflauschig . They once used the comments of one post as the feedback channel as hashtags didn't work. Using this technique, they could make it work.
@evan would that be #quilting@tags.pub or [email protected]?

@inarticulatequilter @evan It's the latter. If you search for it via mastodon.art, you should find this profile:

https://tags.pub/profile/quilting

activitypub.bot

@evan Is there a reason to do this when we can already follow hashtags?

@mayintoronto one reason is because your friend Evan asked you to do it as a favour.

Another reason is that when you "follow" a hashtag in Mastodon, it only filters the content that got to your server for other reasons.

There are three ways that content arrived: either you follow the author, someone else on your server follows the author, or your server is subscribed to a relay.

tags.pub lets you follow a hashtag globally, not just filter what got to your server.

@evan ah, so this would help a lot with say, @introduction for unfederated single user servers.

@evan @mayintoronto

This gives me the heebie-jeebies. "Global" makes me uncomfortable. Automatic boosting makes me uncomfortable. Both are not particularly Fediverse-type concepts.

Here's the intro page on this (note that Social Web Foundation lists Meta and Auttomatic as partners):

https://socialwebfoundation.org/2026/03/17/introducing-tags-pub/

Sorry, Evan, but no thank you.

@jakebrake I was a tad worried about that, but I'm on a server that has threads blocked. If it's just a boost, I'm willing to try it out.

Mostly want to see if I find an uptick in harassment.

@evan

@jakebrake @evan The thing I like about this specifically is that it's an opt-in global booster. So many bots currently boost without our consent.

@mayintoronto @evan

I'm wondering about down the line.

To really work, this system needs to connect to basically every Fedi server, or at least all the big ones, right? Which sounds very centralized to me. And, if it does become a popular thing, gives SWF leverage over the Fediverse: Want your posts "fully" boosted, you need to talk to SWF.

Maybe I'm missing something?

@jakebrake @mayintoronto I totally get the concern about centralisation. I think there are two mitigations for that issue.

The first is that there are two other services that do something similar already: https://relay.fedi.buzz/ and tagpush.

The other is that the tags.pub software is Free and Open Source software; anyone can set up their own server using the software. If you decide to do that (I hope you do!), please let me know, and we can figure out how to share public data.

#FediBuzz Relay

The buzzing ActivityPub relay service

@evan @mayintoronto

Thanks Evan for listening to my concerns and for your thoughtful replies!

One of the really neat things about the Fediverse is that us in the peanut gallery can reach out to folks like you who are building and improving the "plumbing" of the place, and vote with our posts. It is a special thing, and I try not to squander it by overuse or by being snarky or rude, mostly.

TBH, I do like Fedi how it is, semi-useful search and not-quite-boosts and all. So, yeah. 🤷

@mayintoronto The way tags.pub does boosts, we don't share any of your content with servers that you have blocked. So, hopefully, you shouldn't see an uptick in harassment.
@evan @mayintoronto how do you know which servers I've blocked personally? You cannot.
@jakebrake @mayintoronto No problem! Nobody is obligated to use it. It's there to serve a purpose for people who want that feature.

@evan
But Evan, don't you see? If *someone* on the Fediverse doesn't like it, it shouldn't exist!

That's why Mastodon was wiped out years ago by Diaspora users.
@jakebrake @mayintoronto

@jakebrake @mayintoronto Hey, Jake. Your concerns are justified! It's never a bad idea to look at projects carefully.

tags.pub is one of the oldest projects on the ActivityPub network. It was one of the test implementations of ActivityPub. It's been dormant for years; we've been lucky enough to get to implement this with funding from the Sovereign Tech Agency.

The service is opt-in, either by user or by server (and users can opt out if their server opted in). Nobody has to use it.

@jakebrake @evan @mayintoronto I'm with you. No thank you. People can follow hashtags. Nobody is following the accounts that are set up to echo hashtags. It's a waste of bandwidth.
@mayintoronto @evan @introduction and this could give me access to more people in my profession (I find few, right now, using the hashtag #lifecoach)
@evan @mayintoronto This description sounds like following a tags.pub via hashtag is even more limited as it only gets tags from people who’ve opted into tags.pub.
@Chigaze @mayintoronto Yes, it's still in its early stages, but the architecture is made so it can handle more and more content over time. The system is opt-in for individuals, but servers and whole platforms can opt in, also.
@mayintoronto
People on sites running other systems generally can't.
@evan
@evan @_followback @nokings why would you not just follow the hashtag?

@bipolaron

When you follow a hashtag locally on your server, it only filters content that arrived at your server due to following.

So, if someone on the Fediverse posts with a hashtag, and nobody on your server follows them, you won't see the post.

tags.pub is trying to improve that, and bring you *all* the content posted with that tag.

@evan Done; I didn't know about this, so thanks for that.

Reading the replies, it's surprising to me that people don't really understand how tags work here. I think maybe my world view is different because I'm on a single-user instance, so it's much more obvious to me that tags don't always have a lot of reach.

@sean @evan /me goes to convert my hashtag follows to tags instead.

#tagspub

@sean Thanks so much! I appreciate it.
@evan I am so confused. I click on that account and am met with a wall of buttons(?) that say Add. There is one that reads "Accept" but I haven't knowingly clicked anything. I don't see how to simply follow. And when I click on the follow account in certain iOS apps I get nothing at all. *shrug*
@rickscully OK. I'll change the instructions. Search for @_followback in your Mastodon server, then click the follow button there.

@evan I had questions. What is tags.pub? Why would I want it to boost my posts?

https://tags.pub explains most of it. Presumably someone has to pay for this. Is it just altruism?

tags.pub

@edwiebe So, do you still have questions after reading the home page?

It's a project of the Social Web Foundation. We're a non-profit with the goal of making the Fediverse easier to use. We think that if tagged content connects more Fediverse servers, it makes our conversations better and people's experience here richer.

Development and maintenance of tags.pub is sponsored by a grant from the Sovereign Tech Agency.

@evan Honestly, the past decade of social media and, well, everything, has made me very suspicious. The home page explains a lot but the link to the Foundation is very far down at the bottom of the page and without actually clicking it tells me nothing.
@edwiebe So, what you're looking for is more information about SWF, earlier in the page? I can do that. I added an issue here: https://github.com/social-web-foundation/tags.pub/issues/15
More information about SWF earlier in the tags.pub home page · Issue #15 · social-web-foundation/tags.pub

Suspicious user asked to know who's providing this service and why. Found the SWF link in the privacy section, but expected more information sooner.

GitHub
@evan Yes, it’s difficult for a naive mastodon user to understand this. At first it looked like the kind of scam one seems in the spam folder, SEO, buy likes, kind of stuff. I immediately wondered. I did notice your instance name and recognized it as a very unlikely source of spam. Most of the info on the about page is helpful but still I think doesn’t provide what naive users need to understand what this is about. Obviously, I hope, these are my opinions.
@evan @edwiebe I think it needs to explain how hashtags work in Mastodon and what this adds, because I don't think most people know that
Explain why this is needed · Issue #16 · social-web-foundation/tags.pub

Explain why this is different than following a hashtag in Mastodon.

GitHub

@evan @_followback

Hey Evan.

Done! I posted a photo after following, and used two hashtags. Less than a minute later, I got notifications that it had been boosted, once per hashtag. Each boost was from an account corresponding to one hashtag I'd used.

That seems like the expected behaviour, but I figured I'd let you know what it did in case something seems amiss.

Cheers!

@ihember thank you so much! I'm glad it worked.
@evan is it normal than even from a mastodon account there is no followback ?
@rmdes no, it should follow you back. This account?
@[email protected] I followed but didn't get an accept or follow back, so I think there's something up on my end! The relay follow also didn't work so I'll need to take a closer look this week 🙂
@julian OK. I use a separate key ID and actor ID for HTTP Signature, so that can throw off some implementations.
@evan Question -- now that I'm following + being followed by the bot, I get a boost notification for each post with hashtags.
That's going to get annoying pretty quickly... is the intention for me to mute the bot after I follow it? Would that work OK, or does the bot ever need to e.g. private-mention me something I need to not miss?

@evan

OK, I have followed @_followback, so now the #Hashtags I use will be more widely distributed, to anyone who follows @Hashtags rather than just distributed those instances who happen to have someone who follows me.

And I have followed @bikenite so now I should be getting more #BikeNite messages, rather than just those that happen to come to my instance for other people on this instance.

#TagsPub #FollowBack

@evan

Seems to me this service already exists from other servers, eg. fedigroups.social - but that's a good thing, because sometimes these services go away (RIP gup.pe)

It also seems to me that this functionality could be built right into every instance software rather than as a standalone instance. We could use an indicator to differentiate regular #Hashtags from these newfangled federated !Groups...

@_followback

#TagsPub #FollowBack #EverythingOldIsNewAgain

@evan

(Am having fun following all the #Hashtags I create in my usual posting)

(Am also enjoying the high boost counts my hashtag-laden posts are getting)

#TagsPub

@evan followed! will this only boost my #posts with #hashtags or will it also scoop up stuff i boost or other stuff on my server?
@aeva @evan
Based on what I recall Evan saying, it is only interested in hashtags.
@virtuous_sloth @evan I'm asking what exactly I'm #holepunching by #following that bot so that tags dot pub can scoop up those #delicious #hashtags since my server didn't seem to be picked up before via any of the means #outlined on tags.pub
@aeva @evan
It follows relays and scoops up tags from them, which makes it useful for people with their own instances who only get hashtags that their follows drop.

@aeva @evan
I'm less certain about it picking up and broadcasting your hashtags. I think it will, but I don't know about whether, say, it is able to get those to relays so your hashtags are broadcast further.

Apologies for jumping in without concrete knowledge.

@virtuous_sloth @evan it's boosting my #posts with #hashtags just fine, that's not what I was asking about
@evan @_followback One post, 3 tags, 3 responses from tags.pub!
@evan Seems like vanilla Misskey is unable to fetch the profile for the mean time, but this idea is cool
@evan @_followback It worked perfect. My obscure hashtag showed up @cogdogcooltech
