My e-mail address is .

By the way, did you know that putting e-mail addresses on Web pages is a sure-fire way to get lots and lots of spam? It's true—I've studied this phenomenon through several experiments. Whenever one of my e-mail addresses gets out onto a Web page, whether it's an html document or a PDF, spam starts arriving.

So, why would I put my e-mail address on this page in the clear like that?

Well, things are not what they seem. Take a look at the source of this page. Interesting, isn't it? Instead of a link that looks like "mailto: " you see a bunch of code that's unintelligible to spam trawlers. It's generated by a nifty program called Spam Vaccine (follow the link, then scroll down and click the spam can at the bottom of the page). It's only $9 for a consumer version, and there's even a free 15-day demo. How cool is that? So do yourself a favor: Google your e-mail address, and if you find it out there on Web pages, e-mail all the Webmasters concerned and ask them to take down your e-mail address. And do the Webmasters a favor by telling them about Spam Vaccine.
