Spider Blocker
Version: 1.3.7
Description
Spider Blocker blocks most common bots that consume bandwidth and slow down your blog.
It accomplishes this by using .htaccess file to minimize impact on your website. It’s hidden from external scanners.
Spider Blocker is specifically designed for Apache servers with mod_rewrite enabled, allowing you to effortlessly safeguard your website from the most prevalent bots that hamper performance and drain resources.
Plugin Features
- Block Unlimited bots from viewing your site
- Easy Export/Import rules (comes with most common list of bots)
- Zero Footprint
Installation
- Upload ‘spider-blocker’ directory to the ‘/wp-content/plugins/’ directory
- Activate the plugin through the ‘Plugins’ menu in WordPress
- Go to Tools menu and then **SpiderBlocker* to configure
- If you use any other plugin to edit .htaccess file, make sure that content of file is valid
Faq
Will rules stay active after I deactivate the plugin?
No, it’s a good practice for plugins to remove all changes they made to the blog, thus rules will also be deleted from .htaccess.

This plugin doesn't work on any of my installations out of the box.
You need to change
$_ENV["SERVER_SOFTWARE"]
to
$_SERVER["SERVER_SOFTWARE"]
Maybe this should be adjusted ?
Once changed it does its job though!

This plugin does exactly what you think it does if this is the type of plugin you are already looking for. It is very simple and effective.
