On the confirmation of signing up page, it states that the game is targeted at and intended for persons of the age 13 years and older. To create a legal account if you are younger than 12 you must send in a form with express parental consent. Therefore, lawsuits for harmful content to people who are 12 and under are void because there are only two possible scenarios, and in both Jagex has made it so that they cannot be held responsible for harmful content. One, if the account creator who is of 12 years or less creates the account without express parental consent, Jagex could claim, rightfully so, that the account was void and not even supposed to be playing the game. In scenario two, if the creator was under 13 but a parental consent form HAD been sent in, Jagex could argue that the parents-the plaintiffs, knew of the risks upon creation of the account. That leads us to one conclusion: That Jagex is more concerned with revenue than with player's age. EDIT: Also, the people who swear the most are actually the people under 13, because most people 13 and older can think of better words to use than curse words.
