Last month, I set up a private, "secure" e-mail account, and just gave the address to friends and key business contacts. It's been working like a charm - the account works beautifully with the iPhone, and I know that every piece of mail that arrives is high-value, because I've given the address to nobody outside a tight little circle of privileged contacts.
Today, the first piece of spam arrived.
A trusted friend had included my secure e-mail in a mailshot promoting a project. No problem there; it's not a state secret, I'm just trying to keep it safe for useful communications... wish he had bcc'ed me, though.
Everyone on the mailshot who had a webmail account that autoharvests e-mail addresses for their contacts suddenly had my e-mail address. Gmail does this; Yahoo does it if asked; probably others do, too.
OK, still not a real problem there.
Then a woman I know slightly, who was on the trusted friend's mailshot (still following me?) apparently signed up for Quechup, a new social-networking site with a very underhanded modus operandi:
Then guess what happens. It spams *everybody* in your freaking address book, evidently without your knowledge or consent.
