Facebook has been doing this lately.
It appears they aren't allowing new accounts and some old accounts are being hacked down for no just reason.
My private account was equally affected, an account of over 16 yrs. Was notified too to verify the account. After submitting my legit ID, boom I got kicked out.
I sent their customer service a complaint message and uploaded my ID again, up till now have not heard back from them.
As a matter of fact, I feel Facebook is on the path to perdition. They are taking some unrealistic decisions these days.
I don't have anything serious I do on the platform other than to read news feeds of my profile.
And before the account was disabled I had been thinking about how to get rid of Facebook, because it was then becoming more of distraction to me, and when the account got disabled, I didn't fight it that much.
I will advice you leave Facebook for good, except if you're making money through the platform.
Twitter is better in my view than Facebook. Facebook is overhyped.
