Nowadays e-commerce is the new trend compared to the retail stores, but some sellers will manipulate their rankings through false purchases of their own items to boost rankings significantly. The thing is, they cannot do this at the location at where they are opening their seller accounts as the site will save their information. So what they do to make a new account is:
- Buy a new disposal sim card to get a new and unique number.
- Use a different mobile phone (To receive SMS codes as some websites may use metrics such as their ANDROID_ID to detect the device used)
- Use a different and unique PC with a different wifi network to make the purchase. (such as internet rental cafes or public computers)
- Create a one time use e-mail using the new mobile number.
- Pay with methods that are offline without need for identification (such as 7-eleven stores, and other convenient methods that just requires the transaction number)
With this being said, there is almost no fingerprints left behind to find out if it is indeed being purchased by the item's own seller. The sure way to catch them is to contact the person who sold the mobile phone and find the phone's unique identification details as to who the owner of the phone is (assuming the phone isn't stolen), but this is time consuming and unlikely.
What are other ways can the e-commerce website trace these activities?
