Spokeo finds information about your friends—long-lost or not—and then tracks their online activities as they make updates. These friends don’t have to “invite” you, approve your friend “request,” or be a member of Spokeo. Spokeo is able to, for example, monitor their Facebook notes and shares, YouTube videos, Amazon wishlists, Flickr and PhotoBucket photos, Pandora favorites, MySpace updates, Twitter tweets, personal websites, and blogs.
The Spokeo process begins with providing your address book; your name and password at social-networking sites; or the URL of your friends’ profile, photo album, website, or blog. Spokeo then creates a “buddy list” of all the friends that it finds and displays them using a “reader-like” interface. The number next to each buddy’s name indicates how many new entries Spokeo has found. When you click on buddies, you can see the details of their photos, videos, music, shopping lists, websites, and blogs. The sites and services that Spokeo supports are:
