Answer: conducted substantial business with Ohio residents through the Web site.
Explanation: The sliding - scale standard confirms when exercising jurisdiction over an out of state defendant is allowed. It is only allowed when significant business has been conducted by this out of state company over the Internet with another state. In this case the out of state defendant is Trading Post, a Washington company, and it has dealt in transactions over the Internet with the state of Ohio via its website. Because the business conducted in Ohio is significant, it gives Robert the grounds to sue Trading Post, even though Trading Post is not based in the same state as Robert.
