Mark Rober is an amazing YouTuber. I'm sure you've seen his stuff. From a Squirrel Obstacle Course...making a Guiness World Record Elephant Toothpaste launch...and of course the GlitterBombs...this guy has some awesome stuff on his channel.
An now, instead of Porch Pirates he's taking down Scam Call Centers:
It's insane to think these call centers make so much money every year! And to those that were scammed...that's a life changing amount of money they lost. So, help Mark out by sharing the video to your friends like he asked.
And remember, never answer a number you don't know...if you do...let them do the talking first!
