1. Fake spell out your email and let time run out before you're done.
What's just as alluring to a hacker as your phone number? Your email. Start spelling out your personal email one letter at a time. Having this morsel of information dangled in front of them will excite them to no end. But just when they think they have some (more) insider knowledge, time runs out before you're done spelling it out. Ha!
2. Give them someone else to call.
Phone numbers are what they want? So be it! Write down the phone number of the most annoying telemarketer you can think of. Then, Snapchat a photo of it with the caption, "Call for a good time." Classic.
3. Send a creepy photo.
If you're one of the millions of people who had their phone number posted online, you probably feel violated. So much for 10 seconds of privacy and a secret username! Give the hackers a dose of their own medicine by snapping a picture of an ambiguous street corner or window. It should look like it could be anywhere. Then, for the caption write "I'm watching you!" Cue creepy music.
4. Show them what they're in for.
Google a photo of a jail cell with the bars in the foreground. Snapchat a photo of it with the caption, "You'll be behind these soon."
5. Give 'em a good old fashioned shaming.
Take a picture of your dinger in a tsk-tsk pose and use Snapchat's colorful tools to draw a sad face on your finger. In bold red letters spell out, "Shame on you." Maybe, secretly, they're big softies and will suddenly feel riddled with guilt.
