Well.. the latest ban you ever had I could find was on 11/05/13... and the 'first' ban I could find is this: 03/08/11 ...
Hmm... almost 2 years passed by... imo no earlier than 03/08/13. But I should add some time for all the ban evades.. I will add 2 weeks because you evaded twice for sure since 01/01/12.. So your unban is at 17/08/13 if you do not ban evade again.
Also if your 'brother' gets caught playing on our server... it could be you, we will extend the ban with 1 week for every evade you attempt.
