What should we do when we receive spam messages and harassing phone calls?

In our daily life, our mobile phones will receive some spam messages and harassing calls, which we should also be very clear. Our phone number was leaked, because all the current phone numbers were bought by real-name registration system, so we should destroy them in time when we buy the express delivery. However, our mobile phone number is often leaked. For example, some websites that are usually registered, our mobile phone numbers will be accidentally leaked, especially some shopping websites. In this website, any link will reveal personal information, so when we receive spam messages or harassing calls, we should ignore them and delete them in time. Some electronic products have not solved the problem of harassing calls for the time being.

Like now, many people will take part in some street questionnaires. At the end of the filling, some staff will ask us to fill in our contact information, but if we leave our contact information, we will be very worried. People from all walks of life call every day, so when such a thing happens, we can choose not to write our real number or fill in our mobile phone number at will. Now every time we receive a courier, some courier lists will be printed with their personal information, such as some names, telephone numbers, home addresses, etc., which will be revealed on the courier list, so when we see the courier list, we should alter our personal information on the courier list and then discard it.

Now download a software, some mobile phones will ask to fill in personal information, or log in to the website with their mobile phone numbers. In this case, there is nothing we can do, which will also cause our personal information to be leaked. There is no way to reveal your mobile phone number online, because we can't trace the leaked place, and it will also lead to a lot of spam messages and harassing calls. If downloading some software is unnecessary, don't register with your mobile phone number.

Because the current communication is a real-name registration system, for example, when we go to the sales department, the sales staff all ask to leave their contact information, which also exposes their personal information, and the sales staff often make phone harassment through the contact information left. Some people can delete or blacken harassing phone calls and spam messages. At the same time, if necessary, we can take legal weapons to protect ourselves. If this kind of harassment poses a threat to life, we can report our situation to the communication bureau.
