One of the advantages of having my own domain name is that I can give out a different email address to every company that wants my email. I use a pattern to generate these addresses, they're not one-word somethings that a spambot would guess.
Yesterday, I recieved an email from netmarketingcanada.com with links that point me back to netmarketingcanada.com to unsubscribe and view things. They're advertising.. 30% off.. something... my email client doesn't load the remote images (also from netmarketingcanada.com) so I can't see the majority of their email, but that's not the point.
The email was TO the email address that Rogers Canada (and only Rogers Canada) has for me. So, a big thanks Rogers for selling my email address to spammers. I don't remember seeing "will sell your email address to spammers" in their privacy policy, but perhaps it has been updated and someone could point me to that clause?
