The community where hair is brushed is also a community! If the project party clearly stated from the beginning that they do not welcome the act of grooming and clearly stated that the grooming person cannot receive the airdrop, it is still fair and reasonable. But if there is no mention of this in the early stages of the project, and even uses a points system to induce users to invest real money, and then hypocritically refuses to distribute airdrops under the pretext of 'preventing witches', this approach is indeed excessive, not only betraying the trust of users, but also violating the spirit of the contract.
