Our real-time big data processing engine, Guud, was used to capture the number of times the hashtags were used, in order to give the teams credit for the votes. This tool was also used for all of the logistics involved in selecting and contacting the lucky winners of the 10 giveaways via Twitter’s automatic reply feature.
The winners were selected as follows: throughout the period of the campaign, different times were chosen at random (e.g. 10:15 a.m., 1:45 p.m.) in which the first user to send an original tweet (not a reply or retweet) who had not already won a prize would be named winner.
When Guud’s algorithm detected a winner, it auto-followed the user in order to exchange direct messages. An auto-reply was sent to the user with a pre-drafted message along with an image indicating that the user had won the prize.
