One of my competitors has been pulling in hundreds of blog backlinks from all over the place. They are getting these links by posting comments on blogspot/wordpress/etc. I can't figure out if they are using a tool or a workforce. Does anyone have any tips on a tool that can spam more blogs than just Wordpress? (I know about UWCS and the free blog commenting tool on here) -and/or- A tool that can scrape high PR blogs that are open to comments?
