It's the fun climbing equivalent of 'Tick this to confirm you're not a bot' and so doesn't need to actually be complex because that would actually work against the dual purpose of the giveaway - incentivising people to subscribe to brand newsletters and generally informing them/getting them psyched for a certain product release or promotion.
I appreciate you probably know this and are just taking the piss, but doesn't do any harm to answer anyway!
