Here's a novel approach to cutting down on spam: Sow the web with bogus email addresses to bog down the spammers.
At http://periodicos.ws/maillist.html you will find 100,000 email links, all of which are fake. They consist of random-letters-at-random-letters-dot-com.
Newly uploading, one million bogus email addresses, consisiting of random-letters-at-sow-the-web-with-bogus-email-addresses-to-bog-down-the-spammers-dot-com. CLICK HERE.
You can write a program to generate pages like that and add them to your website. Be sure to link to them from the home page, so the spambots will find them.
If we'd all post thousands and thousands of fake email addresses, this will bog the spammers down. They'll have to verify the domain names, at which point, some of us will bog them down by sowing bogus email links with random-letters-at-real-domain-names-dot-com. It's important to use only domain names where this won't cause much problem, where the spam won't be forwarded into somebody's inbox.
Webmasters can select one of these .GIF images and save it as /sowfakes.gif in their site's root directory, thereby expressing to the world their preference. Don't include domain names where there's no file under /sowfakes.gif unless it's an email service or internet service provider.
These .GIF images are in the public domain.
Announcing an art contest! Get your artwork noticed! No pay, no prize, but a chance to have your 60 x 234 .GIF files shown here. They must say the same thing as the .GIF files above say. One very easy rule: They must be better than the ones above. Not too hard, eh?
Send a link to the URL where they are uploaded on your site to: webmaster@sow-the-web-with-bogus-email-addresses-to-bog-down-the-spammers.com.
Webmasters should also add a file in their root directory, /sowfakes.txt, one of the following files: yes.txt or no.txt. This allows people with even rudimentary skills to see which preference the webmaster has. Machines can check the domain name's /sowfakes.txt file to see whether it starts with a Y or an N.
