Bob Wyman, CTO and co-founder of PubSub.com, blog search engine, has posted a blog entry talking a little about his company’s efforts to fight splog.
He says:
I strongly believe that it is in the best interest of our users to filter this stuff out. It should also be noted that we generally will not identify the methods that we use to find these things and we won’t announce (except on rare occasions like this one) which feeds we’re filtering out. If we discuss our identification methods, people will simply learn how to work around those methods. If we identify which feeds we’re eliminating, we’ll be revealing valuable information about our methods.
