How does Facebook comply with COPPA? They obviously accept birthdays during the signup process. So if a potential user who is under the age of 13, inputs an age below the age of 13 the potential user will be denied access to sign up. But if that same user comes back (closes out of the tab/browser and returns back to facebook) with the same email and inputs a different birthday(older than 12) Facebook allows this user to have a profile. How is this not a violation of COPPA when Facebook was clearly aware of the user's first failure attempt to sign up due to age requirement?
