What should I do if I am bombarded by messages from unscrupulous sellers in Taobao?

I really can't help it. The police will definitely ignore it, because you have no evidence to prove that the seller bombarded you with text messages. Secondly, even if you can prove it, this kind of off-site dispute case will not be filed. At most, the police will call to give a verbal warning, and there is nothing the police can do.
