How to evaluate the behavior of merchants sending multiple short messages to users in order to promote sales?

Now more and more people will buy things online, because the network is more and more developed. After some people buy things online, most of the information is leaked. After seeing the information of these customers, merchants will send short messages to these customers frequently. These short messages have caused a lot of customers' dissatisfaction, and some customers don't want to buy anything in this store anymore because of these short messages. In fact, it is those businesses that want to do activities to let customers come to buy and increase sales.

So I sent some short messages to my customers, trying to attract their attention, but I didn't know it would arouse their disgust. In fact, when we register or browse all kinds of software, what traces will be left. Nowadays, many softwares need real-name authentication. Without real-name authentication, it is difficult to buy anything, which makes everyone feel very headache.

If you carry out real-name authentication, it will have a great impact on your own information. Many people's information has been leaked, and sometimes they will receive text messages and phone calls from scammers, so that their money will be wasted. In fact, these things can be avoided, as long as we don't order those softwares, register at will, maintain a very trusting attitude when we hear some calls, and operate them after repeated confirmation to prevent serious losses.

There are some businesses, in order to make customers give praise, so more people will buy in their stores. They always call and send messages to those customers, which makes people feel very annoyed.

If a customer thinks something is good, he can definitely take the initiative to evaluate it. But if he directly calls to harass and sells poorly, those customers will feel that their actions have undoubtedly affected other people's lives. This kind of behavior of returning praise is unnecessary and unnecessary for others.
