It's hard to say. That's the problem with privacy violations. If a store charges you more than the next person for the same item they aren't going to tell you that it's because of data they bought from some third party and there's no telling where that third party got your data from or how accurate it is.
If someone goes to china and they get disappeared the Chinese government isn't going to tell anyone that they were taken let alone that it was because of data they got by surveillance of their mobile device.
