I'm suddenly seeing a lot of bot accounts using the hashtags I use on a regular basis. For example the bio will read

"Follow me if you're interested in the castanwyddeneccles hashtag. I'm a global hashtag sharing bot from tags.pub. When content with the castanwyddeneccles hashtag appears on the Social Web, this account will re-share the content to its followers."

Is this a thing now? I don't think I like it, and I'm blocking them as they pop up.

@suearcher I think the idea is a technical one. If no one follows you on a server, your hash tagged posts don't make it to people on that server, even if they are following a relevant hashtag.
If someone follows the bot, those posts then propagate to that server where they wouldn't before.

@ja Right, I think I see.

I'm not really bothered about how many people see most of my hashtags - especially the ones that pretty much only I use. So I didn't really see the point of a bot like that.

@suearcher yes it is a little odd that it has picked up your hashtags. I can only assume it's some sort of automated bot creator doing it, which does seem a bit soulless
@ja Yeah, it just felt a bit spammy (or scammy).

@suearcher @ja Just for background, because of the decentral nature of our network, if Bob wants to see posts about #knitting, Bob can follow that hashtag but will only ever see posts about knitting that Bob's server (eg toot.wales) knows about.

So if Jane at new-knitting-community.club starts posting using that hashtag, Bob may never know.

Relays and tag boosters (which are a basic component of open social like Mastodon) make Jane's public posts visible to Bob.

@suearcher @ja Following hashtags is something that some platforms like Mastodon and Pixelfed allow you to do, but not all open social platforms have this feature.

Services like tags.pub fill that gap by making the hashtag an account you can follow even if you don't know or can't yet see all the people using that tag.

To preserve boundaries, I strongly recommend using the Mastodon settings for "indexable" and "discoverable" to minimise the footprint of your account to these sorts of services.

@suearcher @ja Lastly, we monitor all of these services, and we allow those that demonstrate standards-based approaches that observe and respect community norms.

Those that do not, or that demonstrate any form of malicious behaviour, we block at the service level, just like we do with federating domains.

@jaz @ja

Ah thank you for the explanation. I'll admit I'm fairly fuzzy on the whole Fediverse thing, so it didn't occur to me that people wouldn't see things even if they were following a hashtag, or that some platforms didn't have the facility to follow a hashtag.

I'm reassured now, thanks.
