If you've ever jokingly wondered if your search or viewing history is going to "put you on some kind of list," your concern may be more than warranted.

In now unsealed court documents reviewed by Forbes, Google was ordered to hand over the names, addresses, telephone numbers, and user activity of Youtube accounts and IP addresses that watched select YouTube videos, part of a larger criminal investigation by federal investigators.

The videos were sent by undercover police to a suspected cryptocurrency launderer under the username "elonmuskwhm." In conversations with the bitcoin trader, investigators sent links to public YouTube tutorials on mapping via drones and augmented reality software, Forbes details. The videos were watched more than 30,000 times, presumably by thousands of users unrelated to the case.
