A McAfee survey of teens and pre-teens finds nearly 90% have witnessed cyberbulling.
That's up from less than 30% last year.
Another key finding, teens are turning to social networks they believe their parents are not trolling, like YouTube and Instagram.
McAfee has some tips to keep your child safe from cyberbullies.
Make sure you have passwords to all social media accounts, and passcodes to all devices.
And stay a step ahead, keeping on top of the latest technology, apps and websites aimed at teens and pre-teens.
Do you think it's important for parents to stay connected this way, or does it cross the line?
