The reason why the score keeps increasing is simply for the sake of maximizing profits. Those who are waiting for the grand airdrop rewards are less likely to consume and claim the airdrop because with too high a score, the chances of claiming the airdrop decrease. As everyone is not claiming the grand airdrop rewards, the score naturally keeps rising. Yesterday, around 225 points, nearly 50,000 people met the criteria, and about half of them did not claim. Today, with over 30,000 people at 233 points, a large portion might be those who didn't claim yesterday. To put it bluntly, these people are just occupying the position without contributing anything, and the key is that there's nothing you can do about them.
