[Meta] What do we do about rape stories?

Reading a submission last week it was clear that if true, it was a rape confession — and after it was pointed out, the poster deleted. And since then, I've been thinking I screwed up not trying to figure out which cops to call.

When it's live, what's a responsible GWS reader to do in a situation like that? Report? Do as much hasty detective work as possible and… then report?

And when they've fled, what then? Reddit's got a record of who what was, including account details (and almost certainly a login/IP log that would tell what campus this was) — is there a path for turning something like this over to someone who can turn the package over to authorities?
