Unfortunately Facebook has lots of information about you whether you have an account or not. You’re a big black hole with known characteristics inferred from those acquaintances of yours who interact with you in a manner Facebook can track. You might not have a name and an account, but there’s a big you-shaped golem in their data and there’s absolutely nothing you can do about it, unfortunately, and they’ll use it as they see fit with or without your consent.
Makes me think of that Junji Ito comic with the person-shaped holes in the rock after an earthquake. Only now, it's an allegory for social media giants and their corrupting influence on the people they lure into their system.
You can I'd you live in a jurisdiction which gives you the right to demand for all information a company has on you, and the right to be forgotten ( GDPR in the EU, maybe California as well?)
In the particular case of Facebook many of us simplify to "don't trust"
There is no upside for Facebook to have anything about me.
