Google has reportedly been locking users out of their own data after what one affected user described as “creepy monitoring.”

“Imagine you’re working on a Google Doc when, seemingly out of nowhere, your ability to edit the online file gets revoked. What you see instead is an error message indicating that you’ve violated Google’s terms of service,” wrote the Washington Post‘s Brian Fung on Tuesday. “For anyone who stores work in the cloud, suddenly being unable to access your data — especially due to a terms of service violation — may sound scary. And it’s really happening to some people, according to reports on Twitter.”

Google has seemingly been setting up tools to read its users’ private data and documents in an attempt to search for Terms of Service “violations.”
