i believe that only people get hack account is believing to get free game....so if your account got hacked it's not steam problem its your problem for download shit stuff...i own steam for 4 years and my account never have been hacked and i had over 30 people put their name adminstration and asking me for username and password and all i told them ok here username is suck and password is mydick...and funny thing that half people did offline...
