Ban after hack?

My account got banned on August 11th due to the reason of CSE and nudity. However I could not think of a single reason this could occur. As my mom’s insta and Facebook accounts were linked to mine, they were disabled as well. I just checked my mom’s email, and it had gotten a security alert at 12 am on the day of the ban(I had been asleep for nearly 2 hours by then) saying that they had locked my account to keep it safe. That morning when I woke up the account had been disabled. I provided the selfie and ID as requested but about 6 hours later I got the final disabled confirmation email. All this time I thought that the AI has perhaps flagged something incorrectly as it had seemed to happen to many people on this sub. But now im wondering whether my account had gotten hacked and that somehow led to this. Or perhaps it alerted the bot to screen my account and led it to find something it didn’t like? I do not care about my account that much, but my mother’s Facebook account was about 18 years old and I would like to recover it, at least. Is the Meta Verified thing the only way to have a comprehensive analysis of this? I’m not sure
