"What are you doing?" is not very ominous. What were you doing, out of curiosity?
If you're freaked by getting e-mail at 3am, you shouldn' t be doing things at 3am that might result in e-mail.
Probably an ethical gray area, but like I said; it ultimately was just a lot of harmless fun. I'm not going to do anything with it. You'll know I'm lying if you see me submit something before 10 PST :)
