What are the steps to discover it knowing ONLY lets say “lemmings.world/post/10530999” and nothing else. If that is not possible, then knowing title “Dead Lemmy instance, how/where to find backup of the post that was on the offline instance?” and mentioned URL, while not knowing parent community name or the instance from which the post originated.

Not local data, question is meant from a regular visitor point of view (not necessarily an instance admin).

OF opinion: good not to be adicted to it or to anything actually.

Thanks, I see that the cross-posting works like this: “In order to cross post, I need to first create the post in one community, then after I create the post, I can click the two nested squares icon under the title of the post (with the pop-up text “cross post”) that shows up on mouse-over.” https://lemmy.world/post/354611

I guess You mean to create new mod rights request discussion topic inside the community, where i want mod rights (seems like an unsolicited way that pings and spends time of all members)

Regarding contacting instance admins in case community has no active mods, i assume i go to parent instance (in this case https://lemmy.ml/ ) and scroll down to see the list of “admins:” in the sidebar. I click one, it says “You are not logged in. If you use a Fediverse account that is able to follow users, you can follow this user.” I am unsure how to follow ext. user via my home instance yet i have found this kind of URL: https://lemmings.world/u/[email protected] (assuming my instance lemmings.world) and on it is a New message button that seems to be working. So it does not seems to be easy to contact custom external instance user who’s post i can not see on my instance. UPDATE: I can do it by using search icon and pasting: @[email protected] (for the community, i use [email protected]) - this method is not apparent to a newbie

no, when i use ! like this: https://lemmings.world/c/[email protected] then it returns error “couldnt_find_community”
