It’s been Said very clearly.
Furthermore, let’s make it real here, do you really think, anyone can Fool Facebook? recently, they also bought WhatsApp and much more going on. their system and ToS very strick, it’s 2020 mate, if anyone tried any trick against them that trick ended up soon. they might be late on reviewing such things but in the end, they will catch it up. ONLY WHEN YOU DO SOMETHING AGAINST THE TOS. they are not fooled and keep blocking you for no reason, Obviously, you have done something, spam, links, misleading of services they provide, multiple IP issue, or repeating the same method over and over again like you keep trying to get an account, throwing links that have blocked, suspicious traffic, or recovering something that required a gap. it does make sense mate.
You must read their FAQ including do’s & don’ts, Follow the instruction regarding your matter, You know what mate? You can’t hide your Real IP from Facebook, no matter you use a VPN/proxy. Do you really think you can fool them? Just do as they told you to do, prove that you’re human not a bot, identity is a must. that’s the only solution. else, cut off everything, never Visit them for the next 60 days, remove cache/cookies and try again but during that don’t visit them, you will be fine I hope so.
Tip: Facebook aware of bots, tricks, so if you use any of them, you can’t stay there any longer, so better creating one original and normal account with the required information. to keep it secure, use approval and email verification security. but never spam Facebook. it’s not 2014’s version, it’s been 6 years now. 
Good luck!
