According to the rules, if the seller is convicted of malicious harassment, he will be severely punished.
Your seller also thinks too much, and being punished by Taobao will greatly affect the operation of the store. It doesn't matter if there are a few bad reviews. If bad reviews can warn other buyers not to buy, then Taobao shop will be finished. The fact is that the bigger the Taobao shop, the more bad reviews it has. So it is no problem to seek a reasonable solution, and willful entanglement will cause big trouble.
