If fake KYC is only done to join the airdrop then it's okay. but if fake KYC to secure your assets on binance or some other big exchange then it will be a disaster, because someday they will find it and your account will be frozen
I don't think anyone would do a fake kyc for an exchange, because by far the exchange is an important part of cryptocurrency investment. Fake KYC may apply to some platforms which always offer promotions on kyc terms but not on exchange platforms.
Although until now I still do not agree to provide identity information to anyone other than exchange, it cannot be denied that it is a measure to anticipate misuse by irresponsible people.
