"He's the hero Facebook deserves, but not the one it needs right now. So we'll hunt him. Because he can take it. Because he's not our hero. He's a silent guardian, a watchful protector. A dark knight." - Mark Zuckerberg, about a good-hearted stalker Likers will like. Commenters will comment. Stalkers will stalk. These are men(or women) on a mission. They are silent observers, agents of the night, stealth warships on the web. The genius of cyber-stalking has been defamed by people with cruel, criminal intentions. I condemn the 'sinners' for using this inappropriately. But we also need a vigilante to protect us. What if you had to stalk 'suspects' to save the earth from an alien cyber attack? What if you're a mom who needs to stalk her kids on Facebook to 'keep a check on them'? What if you're a creep who wants to look at beautiful pictures? Ok, that's the usual one. Anyway, I present to you a salient guide for using Facebook in 'stealth mode'. Be wary, be responsible and use it well, because if you don't, well... surprise! you're a criminal. :)

1. First thing. Hunting your target down.

When you're finding a user on Facebook, basic search by name doesn't always help, because you know, 'R@m@nD33P K@uR'. So you need to resort to step-wise top-down search. The Facebook graph search lets you find stuff like, people from your hometown who like Honey Singh. After you delete them, you can move on with your search for the target.

Put filters like high school, hometown and go on to advanced filters such as things they like and places they have visited.

2. Once you've zeroed-in on the target,enter their extended social circle.

The good thing about Facebook is, you'll find mutual friends everywhere. But even if you don't, add one or two. If you know the target, go down the memory lane; if not, Google search the hell out of them.You'll find at least one deserted profile on a social platform; Hi5, Yahoo, Google+... kuchh to milega hi. Copy contacts from there, follow step one on each, and voila!

Assure that you add the socially awkward, neglected friends, so you don't attract too much attention. Anyone with < 3 likes on their profile picture would do.
