Generates constantly changing webpages a'la the Dada Engine, with faked addresses to pollute spammers email databases.

Similar concepts have been around for for years, including random email generators. Given that spammers are already launching dictionary attacks on sites, and hitting pretty much the entire universe of possible (and a fair number of impossible) email addresses, I'm not sure this will have much impact. Could swing things a bit in concert with other tools, probably won't hurt anything.
