or even better, auto delete EVERY e-mail you get UNLESS you SPECIFICLY know EXACTLY what it is, ie, a friend has sent you one, or its somthing you asked for, or maybe sent by work or uni to inform you of somthing important.

Im very skeptical about anything claimed to be 'free'
NO ONE gives out free things to people they dont know (unless they have a reason to, like spreading a virus, or gaining publicity)
