I've got the same message. And I guess that it was not only the two of us receiving it.
Spamming with PM is not nice (I've threatened him I'll give red feedback for spam if he messages me again), and it shows that:

* he's desperate
* he doesn't really care about rules and being nice

This is how I see it.

I don't know the entire drama, but I trusted that at least some of those giving red feedback did check the proof.
Even more, your post shows pretty much all that's needed. So.. why you bother more than you should?!
