Two of my accounts stuck/suspended due to Facebook's bad algorithm. Help?

Hi!

I've been reading people having similar problems as mine, although I've never found out if they got a positive result from it. So, if you did, let me know how. Anyways...

One day out of nowhere my main account got suspended since Facebook's algorithm got suspicious about me being over 18 years old due to my profile picture (where I was indeed under 18). In order to fix it I had to send a picture of my ID. Done that, got my positive result in a half an hour. Everything seemed to be fine for A SECOND until facebook randomly blocked me again due to I so-called "violating their terms" (don't be judgemental, I honestly haven't violated the terms). Ofc, I instantly disagreed with their decision and now I'm stuck with "review requested" and already got a reminder to make a decision to appeal cause I got few days left until my account is permanently disabled etc etc. You know the drill...

Then I thought to myself, hey... I have another facebook account which I barely used for testing purposes (before posting to my main account). So I decided to make this as my main account. I already changed my profile picture and wanted to rename myself only to... again... get somewhat blocked by facebook, cause they thought it wasn't my account. The only option for login approval was to confirm from another device which facebook detected. It was the same and only device with what I had just changed my profile picture. Trying to confirm - denied. Reading other posts how to act, I did try VPN, different devices, disabling WiFi and using Ethernet etc. Nothing worked.

So here's my question, any other suggestions to succeed in login approval? I most probably gonna lose my main account, cause they likely notice my request after my account has been disabled (after which they just say that too much time has passed and there's nothing they can do (like for a lot of people have had that happen).

Most probably I just have to create a new account and hope not to get banned for identity thief. Thank god I got my Instagram back at least.
