Will SMS unsubscribe be blacked out?

This operation will not directly lead to hacking.

For spam messages, replying to unsubscribe may not achieve the purpose of unsubscribe, and there may even be potential risks. The criminals may confirm the validity of the mobile phone number by replying and unsubscribing.

In order to effectively deal with spam messages, the Ministry of Industry and Information Technology has introduced clear measures, including closing the SMS port that sends spam messages and handling the phone numbers suspected of disturbing people by marketing. In addition, some mobile phone housekeeper software uses keyword masking to block spam messages.
