    I have a question about #activitypub :
    Is there a method for: Following from account xyz only post of a certain type (e.g., images) or a certain hashtag (#abcd).

    As an example: I would like to be able only to see the comics that a comic artist posts, but not their further opinion. (type is only image)

    Another example from the sender side: I am a music group and I would like to invite people to: "Follow #concert_announcement for @mycrazycoolband"

    Maybe @benpate knows about this?

    @benpate Now I think about this 10 minutes longer, this seems like something that one can be done on the client side, right?

      @DePemig The filtering could be done on the client side. But if I were to implement this in server-to-server context, I would probably add a new property to Follow activity, e.g. filter.

        If filters are static, they could be implemented as groups / circles.

          This is one of the features, I want to implement with fedi-herds.

          The main current obstacle for me is: How would you want to specify the filter rules? One would need to develop a way to describe filters on Objects / Activities. Solutions like Pleroma's MRF are just "let's write code".

          If you want to allow users to write filters, you want a more limited DSL...

            @helge @DePemig For hashtags we need a way to say "give me all Notes where tag contains an object with type equal to Hashtag and name equal to tagname"

            There is a FEP by @mariusor that describes collection filters: https://codeberg.org/fediverse/fep/src/branch/main/fep/6606/fep-6606.md. I guess we can re-use those conventions for lists

            Another FEP is https://codeberg.org/fediverse/fep/src/branch/main/fep/5bf0/fep-5bf0.md, but I think it doesn't have implementations

              @DePemig

              Hey Gilles! It looks like several other *far more knowledgeable* people have already chimed in, but yeah.. this would probably be best as a filter on your client or your own home server.

              I *think* Mastodon already does something kinda like this.. allowing you to filter out boosts from accounts you follow. It's a nice add that we could probably expand on.

                Oops, I was celebrating my birthday yesterday and see your replies only now. I'm a bit humbled since I have close to zero technical knowledge about the protocol. However, great to read that my question is interesting for you! 🙂

                  @silverpill @helge @mariusor

                  As @benpate also noted in his answer, an implementation on the client side, be it mastodon on another software seems possible (as indeed, mastodon and other softwares already allow you to follow someone's posts excluding boosts). If I may ask, @silverpill, what information or functionality could be gained by defining this on a "server-to-server" level? You could not create an hashtag that someone "owns", could you?

                    @DePemig @helge @mariusor @benpate Client side filtering works well for public content. But if the content is private, the sender needs to know the audience, so some server-to-server activity would be required.

                      @silverpill HTTP-Signatures work for GET requests too.

                      From them you can extract the actor that accesses a C2S resource and determine based on the resource's recipients (to a reasonable degree) if it's allowed. No S2S required.
