Google is cracking down on apps on the Google Play Store with the most obnoxious ads. The company today announced it had removed ‘nearly 600’ apps from the Play Store – banning them from monetizing ads too – for their disruptive advertisements.

Specifically, Google says that “disruptive” ads are those that are displayed to users in “unexpected ways” such as when ads show up when you’re not actually using the device, or if you get a surprise full-screen ad when trying to make a phone call, unlocking your phone, or otherwise.
