In this Internet age, online dating has become an extremely common phenomenon. If we protect ourselves from online dating, one thing we have to do is not to disclose personal information easily, such as name, address, education, work situation, etc., to prevent criminals from using the above personal information for illegal activities. Second, keep personal privacy, and don't easily tell others personal privacy information, such as marital status and family members, to prevent it from being used by people with a heart. Third, raise awareness of self-protection. If you encounter harassment in the process of online dating, you can delete the other party, and you can report the serious situation. Fourth, self-cleaning and self-love in the process of making friends online is a prerequisite for gaining respect from others and an important measure to realize self-protection.
