[bh4-tech](https://community.nodebb.org/user/bh4-tech) can you supply the URLs you tried to follow please?

[julian](/user/julian%40community.nodebb.org) https://www.threads.net/@khabydistas on threads and https://mastodon.social/@dansup on mastodon

[bh4-tech](https://community.nodebb.org/user/bh4-tech) might be not working because I did not expect urls. Can you try a handle like `dansup@mastodon.social`?

[julian](/user/julian%40community.nodebb.org) Yeah that worked for mastodon, but not for threads. Guess that's some problem on thread's side and not nodebb. However, the remote media preview problem still remains https://community.nodebb.org/post/103782 . Guess you will need to cache remote media like misskey.

My first experience with Federation was with Calckey, (fork of Miskey.) I liked some things about it, but there were forks of forks and I never knew in the end which variant of it was best to use

Hello I am trying to follow some different ActivityPub group and users but but I can't quite understand why some are accepted while others remain "pending." For example, here I was able to follow the profile [skariko@www.lealternative.net](https://community.nodebb.org/user/skariko%40www.lealternative.net) (who is an author of a Wordpress blog) and in fact his posts are posted in autonomous in the category correctly. But if I try to follow another author of that blog like [marcocalamari@www.lealternative.net](https://community.nodebb.org/user/marcocalamari%40www.lealternative.net) or [fediverso@www.lealternative.net](https://community.nodebb.org/user/fediverso%40www.lealternative.net) it remains in “pending”. I have also tried following two PeerTube users who both remain in “pending.” Also after trying to unfollow one of the users it remains in “null.” 

[ska](https://community.nodebb.org/user/ska) there is an issue with category sync with Lemmy, since they do not support categories following their communities. https://github.com/LemmyNet/lemmy/issues/5354 I'll have to take a closer look at Peertube. Are you able to follow those users using your local account, not via the ACP?

[julian](/user/julian%40community.nodebb.org) Those are not Lemmy communities but authors of a federated Wordpress blog: the author skariko is followed while the authors marcocalamari and fediverso remain in “pending”. On the other hand as far as PeerTube is concerned I just tried it and it did not give me any errors, in the next few days I will try to see if new posts also appear to me but it seems so: https://citiverse.it/category/framablog.audio@framatube.org Thank you

Hi [julian](/user/julian%40community.nodebb.org) , and sorry for trying to resurrect this (somewhat old) thread I happened to read. When you said to [hamiller@forum.wedistribute.org](https://community.nodebb.org/user/hamiller%40forum.wedistribute.org) > "I should probably allow categories to track hashtag usage, even if it's local, given how hashtags work." I thought this was now possible. In fact, I thought this was exactly what happens to your "**[General Discussion](https://activitypub.space/category/2/general-discussion)**" category on Activitypub.space. But then I looked in the settings of my federated NodeBB instance, and maybe it's not as I thought. So, I wonder (and ask you): how do you manage to aggregate "general discussion" threads? Is there an automatic way, or do you do it manually with "move thread"?

[informapirata](https://community.nodebb.org/user/informapirata) indeed! This is configurable under the site-wide ActivityPub settings under "auto categorization rules". For that site I have hashtags like "ActivityPub" and "fedimod" set up to automatically categorize discussions. It only matches for discussions that don't already have a category of their own (so, microblog stuff.)

[julian](/user/julian%40community.nodebb.org) great!
