The examples above have no impressions due to the fact they are 'completed' campaigns. Therefor, they should not be able to be found since the only thing connecting the expired campaign to my website is the 'zone'.
Do I have to create a new zone for each new campaign and replace the current zone in order to prevent a 'bot' from clicking a banner in a completed campaign? How can a bot find a completed campaign banner ad and click it unless it's going through the 'zone'?
