It looks like they are indeed AP groups: https://community.nodebb.org/category/gear-engadget@flipboard.com

@AltCode aww, heck yeah!

@julian
Magazines are represented as an #ActivityPub Group. The magazine actor boosts the original post from the profile into the group.

Thanks for the confirmation @jsonculverhouse@flipboard.social, any chance we could have the post list the magazine as a recipient, so that a backreference is established?

@mike@flipboard.social mentioned you, but a typo got in the way

@julian Something seems to be wrong. I've been following a few Flipboard magazines from NodeBB, but it seems like they are not correctly federating with the 4.3.0 beta.

Take a look at [Tech News by @theverge@flipboard.com](https://community.nodebb.org/category/tech-news-theverge@flipboard.com), I've been tracking this remote category for almost a month now, but here on NodeBB, it is still empty. Meanwhile, on Mastodon I see new posts daily.

For the record, this is what an activity created by the group actor looks like:

{
   "@context":[
      "https://www.w3.org/ns/activitystreams",
      "https://w3id.org/security/v1",
      {
         "Hashtag":"as:Hashtag",
         "toot":"http://joinmastodon.org/ns#",
         "discoverable":"toot:discoverable",
         "indexable":"toot:indexable",
         "alsoKnownAs":{
            "@id":"as:alsoKnownAs",
            "@type":"@id"
         }
      }
   ],
   "type":"Announce",
   "id":"https://flipboard.com/magazines/cPVtLWiDRgi0_eWFp_CJVA:m:43611565/activity/DpM9mVh1Qk2oScowFAN8DA:a:43611565",
   "actor":"https://flipboard.com/magazines/cPVtLWiDRgi0_eWFp_CJVA:m:43611565",
   "published":"2025-04-22T09:51:50Z",
   "to":[
      "https://www.w3.org/ns/activitystreams#Public"
   ],
   "cc":[
      "https://flipboard.com/users/theverge",
      "https://flipboard.com/magazines/cPVtLWiDRgi0_eWFp_CJVA:m:43611565/followers"
   ],
   "object":"https://flipboard.com/users/theverge/statuses/DpM9mVh1Qk2oScowFAN8DA:a:43611565"
}

@AltCode I think it's just Flipboard, right?

It might be because of the issue mentioned upthread where items shared by those groups don't have a back reference to the itself so it isn't slotted in it.

They might all just be uncategorized instead. Can you find those items when you search their url or id in the NodeBB search bar?

@julian Yeah, seems to just affect Flipboard.

> Can you find those items when you search their url or id in the NodeBB search bar?

Yes, I'm still able to find them, e.g. https://community.nodebb.org/post/https%3A%2F%2Fflipboard.com%2Fusers%2Ftheverge%2Fstatuses%2FDpM9mVh1Qk2oScowFAN8DA%3Aa%3A43611565

It's uncategorised, just as you said.

Slight tangent, no one seems to be following @theverge@flipboard.com here on the forum.

@AltCode that user and the category are (I think) separate actors. I'm not sure what the user does, shares its own posts, possibly... but like you said, nobody follows that user so I suppose that's why there's not much shown as shared either.

> that user and the category are (I think) separate actors.

@julian Yes, they are indeed separate actors. To be clear, [Tech News by @theverge@flipboard.com](https://community.nodebb.org/category/tech-news-theverge@flipboard.com) is the group actor, while @theverge@flipboard.com is the person actor/remote user, sorry if I caused any confusion.

> I'm not sure what the user does, shares its own posts, possibly...

As I understand Flipboard, users there can create as many magazines as they want, and any post they create must always be in a magazine. It is not possible to create a post that does not belong to a magazine.

When federating this means that each magazine that a user creates is discoverable as @-@flipboard.com; any post that user creates will tag the magazine the post was made into, and the group actor representation of that magazine will boost/share/announce the post.

@AltCode right, I think the issue here is that the posts themselves do not contain a backreference to the magazine they were posted to.

So for example, their latest post has addressed the following:

...
  "to": [
    "https://www.w3.org/ns/activitystreams#Public"
  ],
  "cc": [
    "https://flipboard.com/users/theverge/followers"
  ],
...

... note that the magazine itself is not included, and so when NodeBB receives the object, it does not know to slot the topic into the appropriate category.

cc @jsonculverhouse@flipboard.social again about this one
