I don't know why submitting a vulnerability on those platforms is still free. If reporters had to pay a little amount of money (let's say, 20-50$, or indexed to the maximum gain of a vulnerability in a given category) when submitting their report, maybe those would be of better quality.

I know that this poses new problems (some people can't afford to spend this money), but it would be better than just wasting people's time.
