Easypromos: How to Prevent Fraud in Your Next Online Voting Contest
We’ve launched many contests to attract more subscribers to our email program. While we have extensive development resources, there’s no way we will be developing the contest ourselves. Why? Well…
I’ve cheated in an online contest. Years ago, we had a regional social media contest to find the most famous man and woman in town. After I viewed the source of the contest page, I quickly figured out that I could add a vote just by going to a specific URL embedded in the code. The contest developer thought he was being clever and blocked anyone from the same IP address.
So, I added an iframe on my site that pointed to my voting link. Everyone that opened my page that day inadvertently voted for me. Throughout the day, I would check the voting scores and remove the iframe whenever I got ahead on the votes.
