I love my dog, too, but I'm afraid that won't help. While I assume that you were just kidding when you called your dad evil, you need to know that no one at BC will help you get around his security settings, in accord with this rule:No subject matter will be allowed whose purpose is to defeat existing copyright or security measures. If a user persists and/or the activity is obviously illegal the staff reserves the right to remove such content and/or ban the user.
You can read all the rules here: http://www.bleepingcomputer.com/boardrules.php
I agree with Juha that you shouldn't be too chicken to talk with your dad about this. If you present a well-thought out and reasonable request, he just might reconsider. If he seems amenable, you could also ask that if he hasn't already done so, maybe he would set up separate user accounts for you and your brother and use different parental controls on each of them. (I've never used parental controls, so I don't know anything about the particulars.)
Good luck, and keep up the good work at school!
