Basically what happens is, you link to that page, and the spam crawler follows it. Every time you visit that page new e-mails are generated, they are all goobeldey gook.
So the SPAM bot will add millions of worthless e-mails to its database, and blow up.
Or when the company tries t sell your e-mail, it cant, as its full of crappy fake e-mails, so they'll have to make a new database from scratch.
