Dusty is right, because most of the time us PC users are capable of answering trivia questions in less than 3 seconds, I personally won a trivia hat on an alt account that had 4 hours and everyone accused the admin of rigging it for me but in reality typing on a PC is much faster than iDevice.

Obviously if you have 0 hats you haven't won 20 trivia events.

Also, admins are allowed to participate in other admin events on their player accounts so not sure why you think that is rigging an event.
