We don't know how but it seem something in msn let them access to the account information...
Maybe it's wrong but nearly 5 ppl get hacked (from lvl 50 to 126, with normal or sock stuff) after adding the same person on msn without sharing their account, using cheat with keylogger or trojan or puting account on fake website...
PS : i writing this to prevent more hack if it's true, but if it's false... nevermind !
