In a ban appeal, honesty is one of the most critical things (besides making the appeal actually readable). And where your appeal is concerned, we only have your word, which mostly consists of (as mark mentioned) blaming your brother. We have no way of telling whether that's honesty or not, but considering it is definitely one of the most used excuses (if not the most used excuse), there's reason to believe it's not the honest reason why the glitch was exploited. We also don't know whether your friend showed it to you and you never exploited it, or if you exploited it deliberately numerous times. Just do as Klev recommended, and try again in a year or so (with better grammar and punctuation, because good heavens I didn't need that brain tumor). That's really your best option at this point. An unban is possibly more likely then, but definitely not certain.
