Any other people getting hacked?

They Ip tag you, this would be from getting a message from msn, even a friend invite that you don't accept, from you opening an email from them, too going to a tinyurl link. If they find an email sent by you, they can look in the properties, get your full name, google your information for a facebook, or even find you on facebook. It's basic social engineering and exploitng password changes on the email addresses.

Though yahoo should be the safest, ISP's are unbreakable lol.

That's somewhat odd, since the name on my email actually isn't my name, so no one would be able to get to my facebook that way. I use Yahoo AND I never use it to send emails. Ever.
