anti-spam tool, or not?
As you may know, bots scan Web pages searching for email addresses to add to spam mailing lists. The folks who run this site (in German--translate at Babel Fish) feel we should help them out--by adding a PHP script to a Web page, you can populate it with a number of randomly generated fake addresses (the default is 20), which would result in spam lists clogged with junk.
However, I'm not sure if anna of annatopia--who works at an ISP--would approve. The failed addresses would bounce back, generating extra message traffic for ISPs along the route, I would imagine.
(via MetaFilter, where there are several posts to the discussion thread questioning the tactic's effectiveness.)
