Why did my friend get an email saying I got them banned?

Have you actually seen the email? The enforcement team don't give information about who reports an account.

I got banned today and do not know what for. I did not get an email telling me why i got banned. i just got banned. My gt is xertoic

You will have received an email explaining why you've been banned, depending on the reason it could be days all the way up to permanent.

Basically don't do whatever it was that got you banned, for example don't send abusive messages to people (not saying you did, but that's what most people get banned for)

I know but it was my xbox that was banned not the account, and I did not receive any emails

They also send emails on why it was banned, my friend got a communication ban and it had sent a email so check ur spam folder
