As with most online services, it comes down to trust. There is no means by which Fandom can definitively determine the age of a particular user. If you believe someone may be underage, you can (although you are not required to) report them and staff may choose to investigate. However, immature behavior is typically not considered enough reason to assume a user is underaged. Mostly it just the idiots that decide it is a good idea to brag about how they tricked fandom and they are really only x years old.
