Indeed we should should be able to be more careful in using the KYC. because this KYC more bizarre data field only. do not easily believe, because so far we don't know yet what exactly, is used for the data.
KYC is just Know your customer, so when investing legit company wants to know from where the funds has come from,this is the soul purpose of KYC. but unfortunately some rouge people are using the info and selling it in wrong hands.
