Do we need a FR yet? For one of the free forecast, I made a correct forecast and received 0 rating as a reward. Why?

My previous question has not yet been answered, but I will ask the next one. Did you pay Binance for a listing or was it free at the time?

Of course, they paid, while the wings turned over to binance, the market was booming, and the exchanges asked for the maximum money for the listing, especially binance.
Especially as far as I know, the Wings have no friends on Binance.
I am also interested in the question on the score. If you cancel all the forecasts, the rating will be reset, and suddenly there will still be payments, then how will they be calculated?
