Is it true to negotiate reply Y and unsubscribe reply T?

A media reporter made an unannounced visit to the SMS forwarding platform in the name of a merchant, trying to find The Secret Behind who "unsubscribed back to T", and the reply he got was simply "want to cry": "Even if the user replies to" T "hundreds of times, it is useless.

However, users' unsubscribe responses are sometimes recognized as "active users" in the background, and even "agree" or "register" secretly to increase the frequency of spam messages. In this regard, network security experts suggest that users should not reply or "blacklist" for security reasons.

However, no matter which way is taken, it is a negative response. Users will still receive spam messages from different merchants and different numbers, which is only a matter of quantity.
