The new mechanism is quite interesting, but the effect may be counterproductive because deducting 30 actions means that Binance will not set the score very high. However, this raises a problem: studios open tens of thousands of accounts, each account only claims one, and in 15 days, only 220 points can be brushed. How will Binance respond? Or is Binance's goal to have everyone brush 220 points and claim one in 15 days? This is just going back to the previous 200 points threshold with 15 points on a first-come, first-served basis, running a fast game.
