Buying verified account is not recommendabke in its entirety, it is not safe at all. It can lead to different kind of fraud. Like if binance noticed anything like something wrong somewhere and need additional verification, what will the person do after he has bought the account? This can later lead to the account finally blocked. How about people that will sell fake ones, or in the process of selling legit ones but hijack back the origin, all these are possible. There are peoe that defraud people using the two examples above. While thirdly, explained below.
I think this will be later be used on frauds...
So it's risky to sell accounts especially if there's a real identity on that account.
This is not wrong, buying a verified account means the identity is not linked to the buyer, the buyer can even be from a country that binance support, but need a verified account for malacious purpose which could be criminal in nature, the person can be money launderer or even a terrorist, anything is possible in this case which makes selling of verified account to be forbidden.
