To Mu Mingyu's surprise, most of the initiators of these rice powder charity events were quite sensible and organized, with only a few individuals trying to join the craze and grab some attention.
The official rice powder organization isn't stupid either. They thoroughly investigate all charity events conducted in the name of "rice powder" and then publish the results on their official website, so the public can identify which are the real "rice powder charity events," ensuring no mix-ups.
Those not recognized by the officials (including, possibly, those assisted by Mu Mingyu, Gong Leitian, and others) either received legal letters or were directly exposed by news reports.
Some were dissatisfied, saying, "We're all doing charity, why make such a clear distinction?"
