@julian@community.nodebb.org On Mbin we don't have a button so the user can cross post it to another magazine/community/group. What we count as "crossposts" are just posts linking the same URL (and sometimes title matching, though I don't like that part). But like Rimu said these are entirely different entities with different apIds often from different instances

@julian@community.nodebb.org right now we just collect all links in these 3 fields and select the first magazine/community/group from the db having this url as their public url

@julian@community.nodebb.org Mbin uses all 3 fields for what its worth

@julian@community.nodebb.org Interesting, I though that the audience field was the way it should be done and to/cc fields were just for backwards compat
