Re: Challenge: Ricochet Robots was an anonymous post that was recently edited (emptied) with no janitation history. But
Anonymous Monk cannot edit his own posts. After some back and forth in the CB, the best guess is that the post ran afoul of anti-spam AM-posts-with-links auto-cleaning. Which is fine... but it would be nice to be sure.
More importantly than this specific instance: should there be some sort of indication on such posts, whether in the janitation history or in the body of the emptied post, to indicate that it was auto-cleaned for potential spam? This would give people a chance to weigh in with a consideration-to-edit/restore: "no, I saw the content and followed the link before it was purged: it was a link to a A* algorithm implementation of this problem in another language, which doesn't seem like spam given the conversation". (It's obviously been fixed in this case, but I'm using my reaction to this case to explain the general idea)
