Would it be possible, or even desirable, to post a single thread to multiple communities? I was just looking back on the idea by /u/AgreeableLandscape for privacy violation tracking and ended up in the /c/privacy version, which was dead, instead of the /c/libre_community version with a decent number of comments. I am not saying I think it should be a certain way, just throwing spaghetti at the wall.

Moderation issues aren’t usually a concern for the person making the post, they tend to crop up a few hours later when the arguments start - by which point the ship has already sailed. From a technical standpoint, how such a post would be moderated is something that would need careful consideration.
