Referrer Spam Nightmare

But if you’re busy (or lazy, like me) and you don’t want to have to bother with blocking domains or don’t want to mess with .htaccess there are a number of plugins that you can use.

For WordPress users, there’s Referrer Bouncer which bills itself as a “class of upload-activate-and-forget Plugins”. It’s a great plugin and is really to install. But it only works for your WordPress content so if you want to protect non-Wordpress pages you’re out of luck with this plugin.
