**EDIT**

Following issue is connected to `@a.gup.pe` user. Every federated categories find user `@koirat@a.gup.pe` and follows it showin status _waiting_. Changing the page and returning back shows nothing, that following has disappeared.

Categories can follow real humans, though.

That actor is de facto a bot, and Discourse can’t follow bots — but AFAIK it doesn’t identified itself as a bot. And even the issue would be the bottiness (is that even a word 😳) Discourse shouldn’t let me follow it in the first place (unless Discourse doesn’t know that in that moment). Anyway, it should not terminate following without telling me. Or did it… I haven’t check out logs, my bad.

**EDIT2**

This was all I found.

[Webfinger finds](https://a.gup.pe/.well-known/webfinger?resource=acct:koirat@a.gup.pe) that a.gup.pe-user, so that can’t be reason for that.

—

Is this an edge case, or am I again trying to do something strange?

Discourse can’t follow Mastodon-lists (and those have own issues in Mastodon too). So I tried [a.gup.pe](https://a.gup.pe/) ”pseudo user” instead.

I created `@koirat@a.gup.pe` by following same user in my instance — it will collect toots where is used tag `#koirat` (dogs in Finnish, BTW). That went well.

Then I send a message from Mastodon and both, tag and user, were mentioned. It pop up into list, that followed guppe-user.

In my Discourse I asked category X to follow user `@koirat@a.gup.pe`. I have another category Y following my actor `@jagster@kvarkki.nexus`, it was in status _waiting_. So I was expecting to get that message twice, one from me and one via guppe (oh, for f sake, is that the problem 🤔).

The message sended by my actor was published in category Y, as expected. Category X didn’t get anything delivered by guppe-actor.

When I opened federation of category X, it wasn’t following `@koirat@a.gup.pe` anymore.

So what are guesses:

- `@a.gup.pe` works some different way and Discourse can’t understand it
- I tried to publish two identifal topics from Mastodon (this I can try easily, will take few moments)

This isn’t purely academical issue, because it would solve out list-problems of Mastodon.
