We'd use D&B data if it wasn't so expensive; this is just the demo version. There's a whole industry out there tracking business info, and the search industry isn't plugged into it. (Why? Google gets about a third of its revenue from AdSense ads on other sites. If Google really cracked down on clickbait sites, Google's own revenue would drop. We once calculated it would drop 14-17%.)
Back in 2011, I wrote "Social is bad for search, and search is bad for social".[2] That's when Google had started using social signals for search ranking, and the black-hat SEO industry had discovered how easy it was to manipulate Google via social. Old-style link farming, setting up lots of fake web sites to create links, is expensive, with servers to run and sites to fill. With social spamming, the social network hosts the spam for you, for free! You can still buy "bulk likes" for Facebook.[3][4] The price has gone up a little, indicating that Facebook is having some success in getting rid of fake accounts, but not much.
