The only Blue Post I’ve been able to find was one from Diablo III that stated the e-mail was for reporting exploits you discover and can provide the steps to reproduce.
The nearest one I could find was from Vrakthis (The bot problem - #13 by Vrakthris) and he does not mention the e-mail account either… just the right-click in game and the web form. If that’s where the form goes to, cool.
How do you know that? And that’s a legit question. I looked at the code and couldn’t find where the handler was submitting it too. It’s probably buried in the JavaScript but I didn’t look too hard I’ll be honest.
