I just got banned forever just because I won in a 1v1

Hey HarveyWint.

Thank you for reaching out to the forum. You can see why you were banned and submit a request for a case review of your ban here:
enforcement.xbox.com.

And a quick guide:
How to submit a case review.

You will not know if they are suspended or not the enforcement team does not give that information out to other players.

And just because they have not been suspended yet doesn't necessarily mean they wont be suspended in the future.

if you feel that you should not have been suspended then you can file for a case review at enforcement.xbox.com

The enforcement team does not monitor these forums.

Thanks for the help guys, I was in the wrong and i should not have called him a cat. I just thought that it was a little unfair that i was banned for that and he was not banned for his use of cuss words. I guess ill never know

If you didn't report them, then you may want to.

Even if the other person is not banned yet, they most likely will be. There's no way for you to know for sure when they receive an enforcement action.
