Some people have no idea on what they're doing, but instead of bashing sometimes I tend to warn them and explain how valuable their identities are. Some scammers make their promotions attractive thats why they can always attract their preys.
You are absolutely right. Just create an account in any of the currently active dark market sites, and you can understand the severity of this problem. KYC documents are available to be purchased in bulk, for as little as $10 per document. These documents are in turn used for criminal activities and money laundering, and in the end the victims of the identity theft will be caught up in the investigation. My only advise is not to take this big risk, in order to receive $10 o $15 in bounties.
