Possible reasons are as follows:
1. We only support accurate searches by buyer ID, mobile phone number, and email address. If you do not find it, please check whether the information you entered is correct.
2. 17TRACK has been continuously collecting data on malicious buyers. You did not find this suspicious buyer because no seller has reported this user in the 17TRACK backend. But it does not mean that this buyer is not dangerous, please be careful.
3. If you are sure that this user is a malicious buyer, you can log in to your seller account and report this user.
