would it be possible to have my server subscribed to another server/bot that goes around indexing every hash tagged post such that when I click on or search for any hashtag, almost everything shows up?

#tagspub

I'm demoing #TagsPub at #DwebCamp

I kinda liked (and used!) #TagsPub when it was #OptIn tbh but the #notifications are annoying either way... what if I silence the instance?

@heluecht I wanted to let you know that tags.pub hashtag feed pages are now marked nofollow,noindex. You mentioned it a few days ago, and I added it yesterday. Thanks for the note, and please feel free to let me know if you have other ideas or issues. #tagspub

@evan If Alice wants these hashtags not to be shared by #tagspub, it's entirely reasonable to remove those feeds. But I think you'll need to establish a general rule, and I'm not sure what that would be...

Maybe something like: "If a hashtag is rarely used outside a small group, then members of the group may make a request and tags.pub will generally remove the feed for that hashtag."

Not sure what you'd do if a small group uses the tag, and some want the feed down, others want it to stay up.

On this show, I play a song from Rain Garden; I think a lot about people who live in those remote houses on the highway; there is a power in living somewhere cheap; I feel jealous of people older than me that still have living parents; I got most angry at my dad for not being alive when my child was born; in a weird way, you only become your true self when all your parents are dead; it's unlikely any two of the millions of podcasts have the same workflow; every family is its own weird cult; my father arguing with me about the math of permutations was a big event; if I need an account to read your article then I ain't reading it; I am intrigued by balcony solar; even without storage solar helps with heat waves; tags.pub had a weird pushback; I just block people who bug me and I don't feel bad about it; I fixed my Forgejo action runner on a machine it never previously worked on because I forgot I was fixing the wrong machine.

@cwebber @dweb yes! I am doing a workshop on programming with the #ActivityPubAPI, and another intro to #ActivityPub. I'm going to try to demo #tagspub too.

#DwebCamp

@alice I've denylisted these personal hashtags on #tagspub you asked about:

bunnyalice,captchalice,alicepics

Also, the @AltAfterDark ones:

altafterdark,accessibilityishotaf,hotalt4me,hotalt4u,promoafterdark

There are now no feeds on tags.pub for those hashtags, and if content with those hashtags is received from anyone, not just you, it won't be boosted.

Please let me know if you think of any others.

@seanbala @318133 this is a really good point! ​

@js can I help you guys get the posts hashtagged and integrated into #tagspub ?

tags.pub now has proper blocklist support. If you were previously blocking them over concerns regarding reposting/boosting spam, harassment or illegal material, it should now be a lot safer to federate again.

https://github.com/social-web-foundation/tags.pub/issues/48

@iftas Awesome! They're currently manual, but I've got a ticket open to auto-update. Probably in the next week or so. #IFTAS #tagspub

This is defence in depth -- we still use block-respecting boosts, so if your blocklist goes beyond what's in the IFTAS lists, and you use authorized fetch, users on those domains still won't be able to read your content. But it doesn't work the other way; #tagspub will always block those domains, even if your server is more lenient.

I made some changes to #tagspub over the last couple of days. It's now using the #IFTAS DNI and AUD domain blocking lists, both for sending and receiving data. It will not let actors on those domains subscribe to tags, send activities, or read any data from the site. I've tried to harden the service to blocked domains as best as I could, which might have been too tight -- let me know if you have problems receiving data from the service.

There has been a lot of froth about tags.pub the last few days. I feel like I've already said what I'm going to on that subject. Although I rose to it's defense, it did motivate me to fix one thing that had been bugging me.

I went to extra effort to get my blog/podcast site feeding **in** to tags.pub. That required figuring out Bridgy Fedi login stuff and getting the bridged account to follow @_followback which was a bit of a pain in the ass. Eventually it worked.

However, then the problem was that when #11ty assembled the webmentions for each post which it has been doing dutifully for the last year and a half, those would be swamped with the tags.pub bots. Particularly on my podcast episodes where I have a lot of topics and a lot of tags, the first 15 interactions could be the bots.

So, I sat down and wrote a filter to strip out the webmentions before I render them on the page.

<code>

eleventyConfig.addFilter('removeTagsPub', (webmentions) => {
return webmentions.filter((webmention) => {
return webmention['author']['url'].startsWith('https://tags.pub') == false;
});
});
</code>

It does work a treat. Now I get the advantage of pushing to tags.pub and hopefully increasing the discoverability of my fairly niche indie project while not having to look at lots of "#thistag boosted your post" webmentions on every blog post. Win-win.

@mina
I suddenly got spammy boosts from bot accounts.
I had to find out what this is, why it happens (still dont know. Opted-in somehow by my instance) and how I can stop it.
Older posts with #tagspub said it wasnt possible to opt-out because tagspup even worked around a server block.
Bad communication of Evan ignoring the problems of many people and only stepping back after huge pressure.

I want a big fedi and see social media as essentially about the public conversation and getting attention. I want hashtags to work well here without bots but otherwise can't understand the concern.

#TagsPub

I wonder why everyone seems to hate the tags.pub bot so much.

I mean: Until now, there was no way no get a notification if somebody posts something with a hashtag you're subscribed to.

This is a great feature, especially for hashtags with a low number of occurrences, greatly enhancing the value of the Fediverse for information purposes.

Just asking.

Edit: There's some good discussion below, worth reading. Also including some arguments for being sceptical about this thing.

#TagsPub

"You pointed out how I was violating consent and opting others into my bot-farm against their will and now I'm receiving abuse so f*ck you" is perhaps not the flex the author intended it to be.

#consent #TagsPub #hashtag #ReplyGuy

@evanprodromou

I have been one of the "victims" of the spammy, non-consented boosts from the tags.pub server. It has invaded my server with boosts impacting all my users, with no consent from anyone and no prior information.

I am doubtful about the nature of the scraping, reputedly based on open-registration relays. Because I am not subscribed to any open-registration relay, only two relays which are not open, and to which tags.pub is not listed as participating.

So, how this software is scraping my servers is probably done in another way.

Due to unconsented and uninformed apparent mass-scraping by bots, I have defederated all my Fediverse servers from tags.pub

#tagspub

i block the "trending" bots on sight, and if there's a whole server full of bots boosting posts i'll defederate from it. they have no right to insert themselves into my social fabric #tagsPub

Unsubscribing tags.pub from Open Registration Relays

https://socialwebfoundation.org/2026/06/28/unsubscribing-tags-pub-from-open-registration-relays/

Ciekawa rozmowa rozwinęła się wokół tags.pub w wątku pod adresem: https://lgbtqia.space/@alice/116824281370893420

Niektórzy ludzie są bardzo zdenerwowani, że serwis tags.pub opiera się na domyślanej zgodzie, czyli trzeba się wypisać (opt-out), żeby nie wchodzić w interakcje z tym botem.

Przeycztałem zasady tag.pub (https://tags.pub/) i widzę potrzebę zaistnienia takiego serwisu (bo jest to częściowe rozwiązywanie problemu rozczłonkowania Fediwersum - czyli w praktyce zwykłego użytkownika: mało widać, co się faktycznie dzieje na Fedi). Ale z drugiej strony jest to dość inwazyjny serwis. No i niektórzy chcą lub potrzebuję lub muszą być ukryci w swojej kryjówce i... mają do tego prawo (bez bycia zmuszanym do ręcznego wypisywania się z serwisu, do którego się przecież nie zapisywali).

Twórca kontrargumentuje tak:

if you are being boosted by tags.pub bots, there are one of three reasons:

- you followed our follow-back bot. My guess is that you didn't do this.
- your server operator added tags.pub as a relay.
- your server operator added an open-registration relay.

Unlike other relay services, tags.pub notifies you that you are being boosted, and gives you the option to opt-out.

Czyli rozumiem, że np. moja instancja dlatego jest objęta działaniem tags.pub, bo nasz administrator (@xaphanpl) ustawił drugą lub trzecią opcję z powyższych trzech. Nie rozumiem do końca, jak to działa, ale wygląda na to, że trudno pogodzić masowe automatyczne boostowanie hasztagów i oczekiwanie użytkowników Fedi, że nie będą zalewani niechcianymi działaniami botów.
