It doesn't matter. If 50 people challenge every voter in the state, that's almost 50m reports that need sorted. Ideally, there will be enough outrage that thousands of people will be reporting. Also, manually reporting without using an API to create a denial of service would be the best tactic. The point is to display how insipid the process is, not to cause a denial of service attack.
