Again, not clicking the link.
It's one company (although it seems like there is one similar to it in the article), and you have to sign up for it. Although it can attempt to grab limited data based off of your e-mail address, which means very little if you provide a valid e-mail address that is not tied to any social networks. I have quite a few e-mail addresses, only one of which is tied to my FB account.
Also, read the section in the article about the FCRA.
You're still not explaining anything. You're just posting links.
