the bastards who hacked into my email account and spent the whole night sending messages to EVERYONE on my contact list about "good quality Tv.laptop.camera.PS." etc. etc. ? They included a website address and they have an online "contact us!" chat function.
The one saving grace is they didn't use it to send out adverts for viagra (happened to someone I know. They sent it to all the companies that she was applying to for jobs as they were on her contact list).
