When I open certain small external community that i am subscribbed to https://lemmings.world/c/session@lemmy.ml , i see that moderator list is empty, yet when i visit same community via its parent domain https://lemmy.ml/c/session , i can see one moderator name. Clicking it, cause only page header and footer with no content https://lemmy.ml/u/Seb3thehacker , reloading page (F5) cause error couldnt_find_person. I am not logged in/nor registered on that external instance (lemmy.ml).

So this is confusing, how to become a moderator of an external community? Docs says that i do not need to register on it: "Community moderation can be done over federation, you don't need to be registered on the same instance where the community is hosted". Yet it does not explain steps to do. As I have mentioned, i am unable to contact current moderator. I guess one of my options may be to wait and see if current mod find me worthy and adds me as a mod. But i would like to know other options.
