'Zombie Baiters', as a lot of people call them, will head out into the wastelands, Phone in hand. Often fighting each other to try and take a Photo or Video of themselves with the most gruesome Ghoul they can find. The grosser the Groaner, the more 'Hits' and 'Likes' they're likely to get.
The reward of online fame is enough bait for these foolish wannabes to get up close-and-personal with a Walker.
Be smart, people... don't risk your Brains for a Selfie with a Zombie.
