Seeing as its a different user, vb itself wont check that, i do not know of any current hack that checks different users for the same identical post, you could post here in free requests forum, someone might make one for you or you could post a paid job.
I dont really see that as a viable option anyways, if you site has 500,000 posts, imagine the load that mysql & the server would incur because your trying to check every new post against the current posts you already have.
