Let Web Spammers Expose Themselves
In this paper the authors is concerned with mining link spams (e.g., link farm and link exchange) from Search Engine Optimization (SEO) forums. To provide quality services, it is critical for search engines to address web spam. Several techniques such as TrustRank, BadRank, and SpamRank have been proposed for this purpose. Most of these methods try to downgrade the effects of the spam websites by identifying specific link patterns of them. However, spam websites have appeared to be more and more similar to normal or even good websites in their link structures, by reforming their spam techniques.
