Xbox Live WTF

I was playing on my Xbox yesterday and got booted from a Call of Duty game I was in. I then received a message that stated that my Live ID was logged in at a different location. I thought it weird, but turned off my Xbox to do some things around the house. Later, I tried to play again and when I logged into Xbox Live I got a message stating that my profile had been suspended. Huh? The message also stated that I could log back in today, but it did not say why I was suspended. This morning I called Xbox support and talked to someone that gave me no information at all. So, I check my email and saw one from Microsoft stating that my account was suspended because they received complaints about some inappropriate content on my account. Huh? I have no idea what that could be because I have no idea how I would go about putting up inappropriate content on my Xbox Live account. So, I am clueless as to why I have been suspended from Xbox Live. I don't talk trash, I don't have a camera to take naughty pictures, and I don't post nasty comments anywhere. the only thing I could think of is that someone gained access to my account somehow or someone just filed a complaint against me just to fuck with me. I am hoping that this was some sort of fluke and won't happen again. I would hate to have to start a new Live account and lose all of my achievements and gamer stats.
