Hello,
I do not think the bot is detected.
Create an account with a new IP, a new web browser and change the name of your Windows session, remove also wow cache (and don't download wow client on server website).
Use another profile (a not-popular profile), another fightclass (a simple one) and avoid plugins, I'm sure your account will be not banned.
If you bot on several accounts, don't register account with same ip/webbrowser, and try to run one account per windows install and ip (at the same time).
