Absolutely. You were banned for sock puppetry.
To be specific, no, you didn't engage in any particularly trollish behavior. You were gently and unofficially admonished for a statement that sounded trollish once. Other than that, as far as I could see, moderator action included closing a thread in the wrong forum, a warning for a personal attack, and a request that you be patient and not bump your own threads.
But you're only allowed one account. Violation of that rule results in instant banning. You have no leg to stand on.
