The Xbox One's Upload Studio is an app that allows you to upload video clips of your game footage and according to some reports some users are losing Xbox Live privileges due to the profanity used in their videos. Some have reportedly lost privileges to Skype and other apps, and according to Microsoft the excessive profanity in videos can result you in getting some or all of your privileges taken. These bans are temporary and non-permanent; users aren't getting banned from gaming. Just Kinect related apps and in most cases just the Upload Studio.
Microsoft's statement: "To be clear, the Xbox Live Policy & Enforcement team does not monitor direct peer-to-peer communications like Skype chats and calls. Also, we take Code of Conduct moderation via Upload Studio very seriously. We want a clean, safe and fun environment for all users. Excessive profanity as well as other Code of Conduct violations will be enforced upon and result in suspension of some or all privileges on Xbox Live. We remain committed to preserving and promoting a safe, secure and enjoyable experience for all of our Xbox Live members."
