Great idea! Then post it online for everyone to see
This is just cruel...
Hey look, it's them!
This is hilarious!
Listen guys, what you did is called cyberbulling. It is unacceptable no matter what and it hurts people's feelings. Manipulating photos of people is wrong and posting them without their permission is even worse.
We are very sorry for bullying you and what we did wasn't funny, it was stupid and mean. We will delete the photo.
That's okay... but also remember that whatever you post online stays there forever.
