Here's another clever way for spammers to keep spamming you. Legally they have to include a way to opt out, usually via a link at the bottom of the email. As I wrote a few days ago, sometimes those links cleverly look like phish attempts, so anti-phish measures block them.
Today I got one I could actually click, and did so. It seems the unsubscribe page was (accidentally, I'm sure) so badly written as to crash the browser! Outstanding!
