Interesting to see new type of complaints, all of which looks like overreacting of course over KYC, if you have absolutely nothing to worry about then you could share it, and to fear that your KYC would be sold on darkweb is a funny thing, it is basically a way of saying "I did something wrong and I do not want to share it" and nothing more.

If you feel the same way then you can't be in crypto, all the exchanges are asking for KYC as well, do you fear them selling your information on darkweb as well? If nothing else, do you fear that their data will be hacked and hackers will sell your KYC? If so then you cannot be in crypto, since everywhere you go you are asked KYC.
