Just a technical question, wasn't the ban personal, not just account related? I mean if you are banned, even if you created a new account you are not allowed to post outside meta, isn't this applicable also for the alt accounts too, as the same person is sitting behind them?
I don't want to make enemies here, as I said it's just a technical question related to the application of the forum rules not to make trouble to the OP, rules should be ruled.
