I'm always really hesitant to believe users when they get banned and state why they were banned. I've seen too many instances of "Oh I was just banned for saying this game is bad." and get followed up with a GM posting screenshots of them spamming revolting things in public chats.Hahahaha
Really?
The system is going to sell itself.
Have a busy life? Work, obligations and kids? Get the Xbox One today. Featuring an all seeing eye and automatic parental control. The power of the Xbox One. Always watching, always listening. So parents don't have to.
If they're monitoring skype calls and parsing text/audio at all (much less banning people) yeah that's really disconcerting. But it's more likely someone showed their dick on a stream and is now trying to bullshit their way back onto Xbox live.
