Are you tired of content scrapper? If you have enabled your full feeds, they would easily pull your contents out from your feeds and then inject into their blog posts automatically. And also, they would pretend the contents are written by themselves. AntiLeech helps prevent content theft by sploggers. 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 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, or by IP address. You can enter a User-Agent or an IP address into the Options panel of your WordPress blog. In addition to all of that, AntiLeech will produce a robots.txt output from the User-Agents that you’ve specified in the options page, assuming you don’t already have one. Download the plugin now and prevent RSS or content scrapper.
