Creator Score (was apparently bugged)(probably still is)(seems fully fixed now)

With a score like that, and no information on what affects it, I guess I have no incentive to become a member and participate in the definitely not paid raffle system. It was apparently bugged, my score just went up by 155.1K. It jumped to 172k, and now it's under 100... What even affects it? It's no longer fluctuating wildly.
