I got my accounts back !

Still, it went a bit weird. First, I didn't receive any email telling me I was back on. I just tryed to log an account and saw it worked. Also, I didn't receive the usual email telling me that I could finallize my pending character transfer, even though it was all validated and ready.

So I called Blizzard Customer service. Since the accounts were not locked anymore, the guy had access to my file, and could tell me that I had been banned for powerlevelling activities. He said something was written about extremely fast levelling (I can only guess this is related to my RAF period). He confirmed that the ban had indeed been lifted, and that a note was written on my accounts file saying that I was "only multiboxing". So normally, would another mistake like this one happens, they should be able to correct it immediatly. Unfortunatelly,he told me he could not leave a note warning I am a multiboxer on my other accounts (the ones that didn't get banned).

Out of principles, I asked whether I would be compensated for the loss of play-time. They will credit my account with two free days. Interestingly, they don't do it by default, one has to ask.

Also, because of the ban, I could not use credit card subscription. I anyway had to call them to get that option unlocked.

So I suspect someone opened a ticket saying I was selling characters, some uninformed GM saw my many characters and a pending transfer, and the ban hammer fell ...
