What are the risks of strangers adding WeChat?

Personal information disclosure, harassment and fraud. Personal information disclosure: adding a stranger's WeChat at will risk stealing personal information, such as phone number, address or bank account. Harassment and fraud: After adding WeChat, strangers will send spam, maliciously pull you into the group and commit fraud. For example, I lied about adding friends by mistake, took the opportunity to find a topic to chat with you, and created my own person/white person in the chat. Then I asked for help every day and established an emotional relationship. After gaining your trust, ask you for money to commit fraud on the pretext of proving true love, business failure, capital turnover, etc.
