Make money from blogs - AntiLeech Wordpress Plugin: How to protect your RSS feed from getting copied automatically

For bloggers, a RSS feed is something critically important. With a RSS feed, you can build a set of dedicated readers who get pinged everytime you generate new content, as well as be able to control how much of your post you want them to see. If users are impressed with what they read, they will come to your blog more often to read other content on the blog, and spread the word around. So, having a RSS feed is critical. At the same time, a RSS feed is also a very useful tool in the hands of somebody who wants to make a simple automated system of copying your feed. Such a person will have a website build of content from many similar blogs, and automatically generate content from these different feeds. And since Google does not index RSS feeds, this other site will use a mechanism to take this feed and create a post on the other site. Of course, you hate this, but what can you do, short of stopping your RSS feed. Or you can take the effort to try and identify this person from your RSS feed and block, but it is no easy matter.
Another option is to use a Wordpress Plugin to try and give a different content to such an automated system (called a splog, a blog build from feed spammers who automatically take content from feeds and convert them into content on another blog, hence stealing your content). One way to reduce or prevent such stealing is through using a Wordpress Plugin called AntiLeech Wordpress Plugin (site). What does this Plugin do ?
From the site:

AntiLeech does not prevent the splogger bots from accessing your site. It produces a fake set of content especially for them that includes links back to your site (and mine, too, ok?) and sends it only to them. When they steal this content, it appears online just like normal, except now you've turned the tables on them and have provided them with useless content.
AntiLeech can detect a splogger bot using its User-Agent string (an identifier that some bots send when they are collecting data), or by IP address. You can enter a User-Agent or an IP address into the Options panel of your WordPress blog. When a visitor with a qualifying (any checked option on the options page) User-Agent or IP address visites your site, they will see only the generated content.
