Pictures that do not match the real product. This is one of the most common scams, where sellers trick buyers with manipulative pictures. Once the payment is made, the doll received can be completely different in appearance, the material used, and even in size.
Customers who make an order online (through a website or online store) never receive the doll sent by the seller. The seller maintained a good relationship throughout the buying process, but blocks the buyer immediately after receiving the payment.
The seller will get a real head from the brand manufacturer, and ship it out with a fake doll body (the real sex doll body is soft and elastic, and the breasts and hips should bounce when spanked). The fake sellers will order real heads and bodies, then re-assemble them.
