Two likely scenarios here:
A. He got piloted sometime ago and if the IPs were different, he could easily have appealed a "hacked account" and gotten the suspension lifted when a GM reviewed log in patterns for the moment(s) his account was flagged. Remember, these waves happen due to previous flags, usually weeks in advance of the actual ban.
2. He was among the first to get banned today, meaning the lucky GM/Account Admins he got didn't yet have the information that Blizzard had done a wave today. It's surely a possibility, and very well explains why he might have gotten some warning he's reluctant to post.
Either way, as skeptical as I cam about this, there's little use getting angry at him for it. Most of the users here aren't going to believe him, and 99.9% of the same users aren't going to get the same treatment, regardless of whether or not it's their first offense. If you bot on an account, you run the risk either way. He's not hurting anyone telling his story, and I sure as hell wouldn't post an email either if I were in his position. The time logs would be the #1 thing he's have to present for all to see, and that'd be account suicide given the very public nature of this forum. You'll survive not knowing the validity of his story, as will everyone else caught in the wave. Learn from it, take a good look at your botting practices prior to this wave, and either move on or purchase another account. These things are cyclical, as are the number of people who come and go from these bots and others.
