modrewrite to combat spam attacks
This is a simple ModRewrite i use to combat the file upload, then expand attack that is fairly common with poorly created upload scripts
Basically this reads, if the request or the refferer contains any of the bad words, redirect it to a script called 'nospam.php' (in the root of your server) and give a 404 error, so the page will be removed from search engines.
