What's with the harassment and interception of text messages?

Harassment information has been processed. Interception keywords set in mobile phones are usually some regular and conventional words, numbers and letters. Once a mobile phone receives a short message containing keywords, it will trigger automatic interception, and the "source" who sends these harassing short messages will also realize this, so the content of harassing short messages will be further edited to avoid keywords, so that you can receive harassing intercepted short messages through the self-inquiry service of mobile phone short messages. SMS interception is to intercept messages you don't like to receive, or to cheat junk messages so that these messages don't enter the inbox and avoid harassment.
