you clearly dont know what you are talking about, they scrape the top 10 sites links from google/yahoo etc.... so by saying they are not relevent is like saying the top 10 for any keyword phrase on the planet is NOT relevent.
I didn't say that, did I? So you're spouting even more nonsense than a typical purveyor of scrapers. In any event, even pretending that all scrapers operate in the way you describe (which, simply, is untrue), regurgitating somebody else's SERPs isn't helpful to searchers - if they want Yahoo's results or Google's results, they can go to Yahoo or Google and get them. N'est-ce pas?
