Given how you acted almost every time I met you, and how you acted the first time you got banned, that's an obvious NO. If your brother was barred from the computer, nothing could've stopped you from locking the computer with a password so he couldn't use it. Also, if it was for 3 months, the first time you were banned was back in May, so it couldn't have been your 'brother'. The fact you have the same IP as Jack Joker isn't a coincidence, and another friend of mine had an issue with you doing the same impersonation gag as well. Also, when I met you on your Lag Box alt you clearly knew me. So, I'm not buying this apology for one second. You can keep blaming your 'brother' for this mess, but none of us are buying it.
Also given what Ham posted, I stand by my assumptions.
