One of my competitors was buying links through a network of blogs that were clearly created only for the purpose of selling links. I reported about five of these blogs in separate spam reports and it looks like Google took action against them. The blogs are no longer appearing in SERPs at all. My competitor didn't get penalized, but at least the blogs they were getting links from lost their juice and my competitor wasted their money.
