Use the fake link of Apple mobile phone to get your cloud account password, then lock your Apple id, and then blackmail you to pay! Send a QR code containing Trojan horse through the network. If you scan it, you will be caught. On the major networks, post what small gifts are given away for free, and then let you pay the freight. Of course, the actual gift is not as high as the freight. In the name of making friends online, then all kinds of appointments are actually all kinds of delays. All of the above are common in our life. As long as we don't have the mentality of being greedy for petty gain, we won't be fooled. The most important thing is to remember that there is no free lunch!
