I was playing call of duty earlier today and this guy said he could hack my account and 'leak my information'. I told him I live in Colorado but thats it. I have Colorado on my profile. The guy said he knew my IP address (I dont know my IP?) and said what city I live in and was correct. I did not tell him my password or my windows live id password. I still have control of my account. I know they guy's gamertag. What should I do?
