Your friend should have been cheated by buying an account, right? If you buy goods or WMB, you won't be cheated unless you have his signature and then he applies for perfect search. But there are few boring people, and perfect retrieval is also very troublesome. No one will apply for a perfect search for this thing. Be careful if it's an account. The first recommendation is the diamond account number, guaranteed by 5 173. You can't get it back if you buy it. Also, if you want to buy other accounts, try to buy one that is secure, with a safety factor of more than 4 stars, with a scanned ID card, and also provide an email address to support the modification of the email password. This number is basically hard to find. After you buy it back, spend 60 yuan to change the super identity verification code, then change the password, fax the email address to yours, and bind it with a secret security, which is basically difficult to find back. Even if he has an ID card, he needs to fax the super identity verification code. Even if he wants to change the verification code, he doesn't know your email address and password, which is much safer. If the above conditions are missing, it is best not to buy them.
