Custom Gamerpic

On my iPhone I have the xbox app and when I go to change my gamerpic to a custom gamerpic for my account a message pops up saying, "Because of your past behavior, you can't upload custom images. Learn more at http://enforcement.xbox.com." Is this a permanent
thing or will it go away? All I want is to change my gamerpic to a normal picture, nothing about it is offensive and I really want it on my profile. For the past behavior part I have been reported on communications twice. I'm done with how I used to act because
I know it's not worth the penalties. In the end I just want to know if I will be able to change my gamerpic any time soon.
