AntiLeech Plugin To Stop Splogs – Does It Work?

Ajay wrote yesterday in his weblog tools column about the AntiLeech plugin that stops splogger bots from:

accessing your site. It does this by producing a fake set of content that includes links back to your site and sends it only to them.

Does anyone have any experience of using this plugin that they can share? Splogs drive me mad and I hate them using my posts, so if the AntiLeech plugin works I’ll install it straight away.
