"Defamation" is an obscure term for harassing calls in the industry. How do callers get the user's phone number?

Everyone may receive a lot of harassing calls in their daily life. How did he get the phone number of the user? Some enterprises themselves are harassed, and some ordinary individual users are harassed. There is an industrial chain behind this. So we are divided into two parts, one is an individual and the other is an enterprise.

Individuals will be harassed, a large part of which is the mobile phone software we use now. He leaked our information behind the scenes. Originally, no one knew our personal information except ourselves, but we used it through mobile phones, like your app. These apps will quietly record everyone's personal network trajectory in the background, such as which interfaces they like to browse and what types of content they like to watch. This is the smart recommendation of big data. But at the same time, our own mobile phone number, personal preferences, shopping preferences, and even aesthetic preferences, family environment, spending power, these information have been leaked out.

Enterprises will be harassed, which means that many enterprises that have started their own businesses are not particularly large. Within a few days, many companies that provide related services to enterprises make harassing calls to themselves every day, saying, what kind of service do you need? Where do you think this information came from? Judging from the official website of those enterprises, this official is quoted, and it is definitely not from the Industrial and Commercial Bureau. Then, who is looking for these things, these companies that need corporate contact information and make harassing calls, can get the right to export corporate information by purchasing members.

After that, our personal information is actually quite difficult in the internet age, because according to the current network trend, unless we don't use any smart devices, our personal information will definitely be leaked, so we will often receive some spam messages or harassing calls. If it is particularly serious, change your mobile phone number. After all, most people communicate through social software now, and fewer people communicate by phone every day.
