How to know who your facebook stalker is wiithout giving my phone number?

[Carley]

Or getting a virus. Theres guiz ones but they always seem to ask for a phone number. And when I click on an app that supposedly finds stalkers but don't do it, how do I know if facebook puts that stalker thing on someone elses page. Like someone posted a thing saying the names of their three top stalkers and I asked them about it and they weren't even aware that they posted it on my page!
