1.)They are a hacking clan that also plays CS which well....you get the idea.
2.)Pretty much KiNG explained that one.They are one of the main suspects of stealing the source code.(I think)
3.)Like before they are hackers and the pirate software and this website does not want anything to do with them or want the word "M Y G O T" all over the forums.
Basically there pussy ass hackers with no life who wants to ruin everyones fun playing CS.Which cs is not fun anymore, so it does not matter.
