After a few hours of checking everything I could this is what I have learnt. He has a static ip which changes every couple of months or maybe every year. Obby renamed to Monk3y sometimes better being a T for <E> and 9th March 09. For me I believe he did it whilst a T at <E> since if it was after and reliving for old time sakes, he would have most likely used the full tag. This would have been 2 years ago. Which explains why it was thought to be someone else at the start.
For the time being he will remain suspended, this means he can not use the tag in-game or scrim with the clan.
Thanks to Comprichard, Smokey, Purple, Asian, Bk and Merky for there help.
