To use SportsChimp, you must be at least 18 years old and a resident of the United States. By using SportsChimp, you represent and warrant that you are least 18 years old and a resident of the United States.
Isn't this weird? Not only are they saying it's illegal to use this from outside the US, it is inside the US where they'll have the most trouble making this work. These terms were probably lifted from some app/service where they made sense.
