I knew that in Germany contracts with minors are voidable. After some checking they apparently are voidable in the U.S. as well:
reply> Contracts with minors are voidable at the minor's discretion but exceptions exist, such as contracts for necessities (e.g., food, health, and transportation).
Presumably companies can't enforce debts against children [who are under the age of criminal liability, which is under-10 in UK].
replyCould they enforce them against their legal guardians (under the theory that they have neglected their duty to supervise their children appropriately) though? I think this is a thing in at least some jurisdictions.
replyIn Poland legal guardians are responsible for neglects in guarding child. What is "proper custody" depends on child age. Parent cannot close child in basement, it is expected for child to have freedom appropriate to is age.
replyI doubt that AWS could justify that part of proper child custody is to watch what child do with newest AI feature dedicated for processional IT. AWS neglected proper verification of user age.
