Yep, I’ve had exactly the same thing happen to me. You might be able to delay it slightly if you use an email address they have in their records from other users (i.e. an email address some of your friends have stored for you in their contacts they’ve shared with Facebook). Set up a new gmail / Hotmail account they have no trace of existing before, the red flags go up and it will almost certainly get you to verify with some form of government ID, real phone number or possibly both.
I’ve supported Oculus since DK1 through every single iteration of hardware. This change by Facebook has just killed the brand entirely for me. I simply won’t sign up / back into Facebook (killed my account around 2011 as I found it overwhelmingly toxic and have never looked back) to use a piece of hardware I already purchased.
