I have developed a tool that scrapes articles from ezine and associated content, scrapes images from flickr , videos from youtube and authority links from google and mixes them randomly at sentence level, paragraph level or article level in exact quantity and variations that you specify. You can generate output ready for SenukeX, Xrumer, BMD using XML templates. I was thinking of using it and selling keyword based content in BST but my partners thread in pending approval for a month. Meanwhile you can have a look at my fiverr gig by the name of stinkingrich.
