Great idea to reward helpers! I would love it if you could take that on and I'd be happy to help you out with some POINTS for prizes!
This challenge rewards engagement and activity. It takes a lot of effort to be in the top 50 of the Ecency Leaderboard. Each week Random.org is used to generate 5 winners from those in the top 50, as explained in the post. The challenge has been going on for some time and I'm pleased with how many rewards we share with Ecencials each week!
Hope to see your name in the top 50 on the Leaderboard someday!
