It has been a few weeks since I was given a 48 hour suspension, but I am just as confused about the matter now as I was back then. After several emails to Blizzard's Account Admins that turned up nothing, I currently find myself awaiting a response to a thread I created in the official Customer Service forum. I know that very little is likely to be solved this way (as the CS community as a whole has reminded me several times already), but even if a Community Manager offers me very little help, it would be more than I have already received. So really, I've got nothing to lose.
Unfortunately, after some promising amounts of activity, the thread has fallen through the cracks, and a Blizzard Blue has yet to respond in it. It's still early and just after holiday, however, so there is still hope.
I'll update as things happen, and thanks to all who have already offered their support!
