Wpoison - Prevent E-Mail Address Harvesting
	Wpoison is a CGI which can be used to help reduce the problem of bulk junk e-mail on the Internet. Wpoison helps to combat the junk e-mail problem by thwarting the efforts of junk e-mailers who regularly scan web pages, looking for target e-mail addresses to harvest (which they subsequently bombard with junk e-mail).
	Installation
	Do the following, depending on your Virtual Private Servers O/S. FreeBSD & Solaris Connect to your Virtual Private Servers via Telnet or SSH and issue this command: % vinstall wpoison Add the mod_rewite Apache Module to your web server by including the following line in your web server configuration file (~/www/conf/httpd.conf): LoadModule rewrite_module modules/mod_rewrite.so
	Usage
	In order to properly implement a site inoculation, you will want to use a combination of empty <a href> tags on your home page and throughout your web site a la <a href="/leeches/index.html"></a> as well as add the lines similar to the following to your web server configuration file: RewriteEngine On RewriteCond %{HTTP_USER_AGENT} ^ExtractorPro.* RewriteRule ^/.* /leeches/index.html [L] RewriteCond %{HTTP_USER_AGENT} ^EmailSiphon.* RewriteRule ^/.* /leeches/index.html [L] RewriteCond %{HTTP_USER_AGENT} ^eCatch.* RewriteRule ^/.* /leeches/index.html [L] To prevent legitimate Web Robots from indexing the Wpoison generated pages, create an entry in your robots.txt file (or create the file in your ~/www/htdocs/ directory if it does not already exist) to "disallow" the /leeches/ directory, like this: User-agent: * Disallow: /leeches/
