Many ToS often contain disclaimers all over the place to the effect of "this doesn't apply in cities/states/provinces/countries where the law says otherwise" and catch-alls to that effect. Sometimes that's enough, sometimes not; if the company still tries to enforce rules in a region where they are invalid then the ToS is simply even more meaningless.
