Automatically add staff notice about duplicate on the internet?

@Arjan

I think, but will need to find examples, that I also saw the review being triggered for existing posts, after it was duplicated to Stack Exchange.

@maiki I’ve not run into examples to confirm this seemed to have happened. Surely Akismet flagged existing posts as spam after some time passed, but I’ve no clue about its internals to determine that.
