Why do I get banned for a girl in sweat pants and a crop top as my pfp

You would need to go to to the enforcement site. https://support.xbox.com/en-US/help/family-online-safety/enforcement/how-to-submit-a-case-review

they denied it but they PERMA banned for a pfp not cheats not doing anything else a pfp a bit to much for a pfp of Osama bin ladder not ladden they could of at least banned me from changing my pfp not ban my whole account.

By posting an appeal, I can ask questions reasoning why my pfp was ban, right?

Hey Chase!

Nice to meet you! I'm Darhyl, an Independent Advisor. I'm sorry you are experiencing this. I am here to help.

Just a friendly reminder that for enforcement actions there is a dedicated team that handles them which is the enforcement team. I’m sorry but the reason and all details are only available on your end.

The only best option is to file a case review if your account is eligible, here's how:

Sign in and visit the Enforcement history page. https://support.xbox.com/en-US/help/family-onli...

Note If you’re a member of an Xbox family group, an organizer in your family group must sign in to their Microsoft account to review your enforcement details before they can submit a case review on your behalf.

If you’re an organizer of an Xbox family group, you can choose the gamertag of the account that you’re reviewing under Viewing enforcement history for. Under Enforcement history or Active suspensions, you may find active enforcement for your account or one that you’ve selected.

Choose an enforcement action to review more info about the cause and effect of the enforcement in the pop-up window.

If the enforcement action qualifies for case review, you can select Submit an appeal to receive more info from Xbox Safety.

After you’ve completed the form, select Submit.

Thank you for your understanding and kindness. I hope you have a great day!
