How to treat not sending commercial short messages without users' consent?

Please, there are still people alive here.

As long as you buy something online once, the store will send you a short message regularly, with an unnecessary sentence: "unsubscribe and reply to TD". I hate text messages, but I never dare to reply.

I don't know if someone else said it or I thought it myself. Even if you give an unwanted reply, you will enter a new routine, that is, you have the potential of active users.

Why? Ask why it is an active user, because no one replies, and replying to unsubscribe is also active; Second question, why do you want to unsubscribe? Unsubscribe is an introduction, and people then ask you why you want to unsubscribe. Where can we improve? What do you think of us?

It is necessary to introduce new methods, otherwise it is not easy to answer strange calls. When you answer this call, it is equivalent to saying to other businesses: Come on, this person has been chatting with that company for 5 minutes, so hurry up and develop.
