See Who is Stalking You Scam: How It Works
Either on Facebook or Tumblr you receive a message on your profile, as a recommendation coming from one of your friends. Your buddy suggests clicking on a link to see who is virtually stalking you.
The text might be similar to this: "W000w!! I Cann0t blv that you can now findout wh0 is been Searching at your profile for real! You can easily find0ut who is spying on you at–> (compromised link).
If you do click on the link, you're taken to a page that requests your permission to access private information. When you do so, the message immediately reposts itself on all your friends' walls and you're prompted to fill out a phony questionnaire. You won't see your Facebook or Tumblr "stalkers" whatsoever.
This is caused by an app that you just used by clicking on that link. The whole thing is a scam to trick more people to installing the spamming app and clicking through to survey pages.
