Regardless, there is still a digital fingerprint you are leaving of which a profile can be made about you by the Intelligence Community.
If you are asking does FB forward that information, I will say no not directly. But indirectly yes by any friends who do use FB. Example: your contact number, any photos you are in that they upload.
Also other companies such as Google can forward a digital fingerprint of you regardless if you create or do not create a profile with them.
With today's exposure to digital devices it won't be so paranoid of one to think that the possibility of everyone has a profile on them.
Think of the Intelligence Communities profile on any given digital fingerprint as an entry into a vast encyclopedia which can be referenced when required. Does anyone know you have jacked off to tranny porn before. No, However if you are flagged for what ever reason and the retrieve your digital fingerprint they will see that bit of crust you missed when cleaning up.
