Simple .htaccess Rules To Block Spammers

You can easily and effectively use your .htaccess file to easily and effectively block comment and referrer spammers targeting your blog(s). If you are using WordPress you can also use my Referrer Bouncer plugin, which is much simpler, to block referrer spammers. For the rest here is a sample .htaccess file you can start with.

Note: I use this file within my Apache server configuration file (httpd.conf) which may not be available to everyone. Keeping it in .htaccess is mostly a safe bet (that it will be available).

Customize this to your needs.
