Hmm, in Germany children and teens can still enter contracts, as long as they are able to pay it with their monthly pocket money. Every single thing you buy here in a supermarket is also an implicit contract (Kaufvertrag).
So, you could theoretically rent servers and buy ad space on Adsense as long your pocket money covers it. On the other hand: this is a liability for Google and $provider -- as most of them are post-pay. If a teen ever decides to spawn an A1000 instance with 36 cores and cannot pay, the contract is void and Google has no entitlement for compensation.
Pre-paid stuff like a small instance on vultr.com should work fine, though.
