What I tried
First of all I tried the self help tools (lost your password? your account was hacked?) but nothing worked.
Sent emails to:
Wrote a letter to the Italian Data Protection Authority and Tv Shows...
I tried this form for EU users, but Meta replied saying that they don't even recognize my account. I know some people had luck with that
I also filled out this form of the Data Protection Office of Facebook, but they answered giving me a list of self help tools I cannot use
Some users are paying Meta Verified to get their account back...
How I got it back in 10 days
I just got my account back, I received a code on the email that I gave to the Utah AG and bam!
I really hope this won't happen again
