At one point or another, they're gonna start trying to charge the guy who's phone number you gave them. If the guy denies ever signing up for a Runescape account or if it turns out to be a faux number, you're going to get banned from the game.
Aside, I don't find ripping off a company to be particularly conscientious. Or smart.
