I suspect you ran into someone who reported you with certain keywords in the complaint. A cursory examination of your account might have confirmed one or two details and that was enough for a temporary ban while further investigation ensues.

I'm at a loss for any other explanation assuming you're telling us the whole story (and I have no reason to think you wouldn't be ). I've long wondered if there were "trigger" phrases you could report someone with that would result in an immediate, if temporary, ban on the other party. I'm wondering if Oltecs is at least partially right about GM involvement in the report. :P

If you haven't already, I'd follow the poster's suggestion in your previous ban thread and petition a GM to make a note in your files for your accounts that you're a multiboxer so they'll at least flavor their investigation(s) with a modicum of restraint.
