With stricter Facebook settings, it's much easier to identify whether people know you or not before accepting their friend request.
But what if someone who looked, posed, and had the same name as you asked to be your friend?
Ryan Roy decided to prank some strangers when he searched for people with the same name as him, and then copied their Facebook photo before sending them a friend request.
The prankster was disappointed when people failed to grasp the joke:
"none of them really got it, they just got really creeped out and changed their profile pic immediately."
With identical looking poses - costume and all - we see why users found it a little strange...would you have accepted the friend request?
