The difference between all the other clans and this specific one has been said on the officials... They come back every few months, baba up bigtime and play Cz for a few months before leaving the server again. The dumb part was that THEY got a CS and started bragging about it everywhere, with the intention to sell it for USD on ko4life and Pelos saw it... The rest can pretty much be read on the official forums.
I have no idea how this is going to end, but belive me... I'm excited!!
