Move a specified amount of spam.

There is a special system in the background of mobile system to monitor advertising messages. Basically, it is set to push short messages to hundreds, thousands or even tens of thousands of users at the same time, which will be defined as spam users. Of course, if it has been filed with the mobile and related departments, it can be released, but there are only 6 or 7 short messages like yours in a row, so this phenomenon should not occur. I suggest you call the mobile customer service staff directly and complain about them.
