In the Summer of 2016, Constellation Brands launched Corona Beer's "Raise Summer" 2016 Sweepstakes where entrants could win a bunch of awesome prizes from Spotify, Drizzly, Uber and their own eCommerce shop, Corona Merch.

The previous year the Alternate Mode of Entry (AMOE) form had been breached so I built a mechanism that employed a hidden unique signature for each entrant, making form sharing impossible. Even with 3 million entrants per month, there were no AMOE incidents that year.
