People widely use programs like ScrapeBox to build backlinks. Sometimes, it is believed that one cannot compete without such backlinks. An important action is to post links in comments to blogs. I think having good list of blogs for commenting is more important than the software. However, there are common lists as everybody use. I wonder won't search engines (like Google) trace these lists and penalize backlinks in comments? As I checked some of the blogs in the autoapprove lists, they have hundreds of comments with links. How program like ScrapeBox can be used to post safe backlinks?
