Right after I got the "message" (when I want to log into Facebook there comes a pop-up that says that my account is blocked), I tried to create a new account with another email adress. But I couldn't create one because they probably  also blocked my name and date of birth.

A few months later on the 20th February 2018 I tried again and I was able to create an account. So I started to arrange my account, started adding friends and reistalled the Facebook app to my mobile. After like 30 minutes they also blocked this account without telling me a reason why. So I completed the for https://www.facebook.com/help/contact/260749603972907 again and wrote an email.

Dear Facebook-Team, after 3 accidental copyright infringement *(report numbers see below)*
against Universal Music you deactivated my Facebook account on the 8th of November 2017. Last week I had a long conversation with a Senior Director in Music Licensing from Universal Music Publishing Germany who explained me the
whole cover video thing and now I finally know how it works and what is (not) allowed. In the last few months I tried to contact you a dozen times through different email adresses, social media etc. but got no answer.
I have to know: Is there any chance to get my account back? Or can I create
a new one without you deactivating it? (As you did with XXX@XX.de)
Friends told me to create a fake account but I don't want to do that.
I was a Facebook user for around 8 years and I'm only 22 years old, so I will need an account in my future, too.
Please help me!  Yours sincerely - Sarah Fischer

Hi, you let that sound like I did it on purpose! 

I really didn't want to do that, but in March I decided to create a Facebook fake account to be able to do at least some stuff on Facebook.

Also I sent a data request to Facebook 2 times at the end of February.

On March 12th they told me to send them a photo of my ID. I instantly sent it. On March 15th I got an email with a link to download my data.

Dear Leah, I've got 3 questions/concerns:
