A minor's ability to contract at face-value is straight forward, any contract with a minor that is not for necessities (food, medicine, clothing, and lodging), and was not approved by the parents/guardian, can be dis-affirmed by the minor as long as its before they become the age of majority.
But how does Facebook handle their agreements with minors?
Facebook, a social networking site that allows minors thirteen years of age or older to use their site without parental supervision (in compliance with COPPA); Facebook receives it's revenue from collecting personal information about its users and targeting the user with ads that might line up with their values or interests. Although Facebook is in compliance with COPPA, it still holds agreements with individuals that have not yet reached the age of majority, and uses their information for things like "testing" and "research".
Can Facebook legally conduct these "research and testing" activities with minors and their accounts if the contracts(TOS) with Facebook's users that aren't the age of majority are considered voidable/unenforceable?
UPDATE
It seems as though Google, YoutTube, and other large tech companies (e.g. tiktok) have been found in violation of COPPA, with this new information can FaceBook conduct their "research and testing" with minors information without violating COPPA.
