Spam Irony

In my spam research today, I came across this link to a blog post discussing POPFile, a POP3 spam filtering tool. I've seen the tool before, and I'm not even sure why I bothered to read the post, but I'm glad I did. This bit from the end caught my eye:

Steve Shaw is the developer of PopUpMaster Pro, which allows you to add unblockable popups to your web site quickly and easily, specifically designed to sign up subscribers to your list, and fast.

It's good to see that the marketers are not immune to the problem.
