Louise Matsakis, writing for Motherboard: Google Docs, the collaborative, cloud-based word processing software, appears to be randomly flagging files for supposedly "violating" Google's Terms of Service. A member of Motherboard's team, as well as numerous users on Twitter, report that their documents are being locked for no apparent reason. Once a document is flagged, the owner of that document can no longer share it with other users. Users who have already been shared on a document that's been flagged are kicked out and can no longer access it. When a draft Motherboard article was locked on Monday morning, a message took over the screen that read "This item has been flagged as inappropriate and can no longer be shared." It's not clear why this is happening, but it may be the result of a glitch in the system Google uses to monitor Google Docs. DownDetector is currently reporting Google Drive problems in the US and Europe, which may be part of the problem.
