I came across this piece of software called 'PayPerSeed' which is used for scraping certain keywords and creating backlinks by posting a comment with anchor text. I don't usually bother with automated software but we're launching a series of mini websites and I'm thinking of using this to give them a quick SEO boost. The software comes with a 6 week money back guarantee so I suppose I don't have a lot to lose except time! If anybody has used this could you let me know what you thought. Thanks.
