They didn't mention it on the emails at all. It was the contrast between 'my son is named x' and 'i kill u' that scared me. What I should have mentioned in the blog post was that there were other messages they left as comments in the code they submitted. So at the moment you have to leave an email address to take an open test. (This will change soon to no address required). The guy consistently signed in with a fake email address, email to which was bouncing. I blocked that email address, which amounts to not accepting it to let someone sign in for an open test. This is just a soft warning, of course. So the guy appended a character to the address, and left me the message: "Why have you blocked test@example.com? Too bad codeboffin!" I just don't see why they couldn't have discussed it on email on which they were already in mid-conversation with me. I presume the social engineering was coming. I would probably have told the person anything he wanted to know about my security setup by then. I don't think I would have been as open to anyone else off the bat.
