First, treat the victim like a pig. This scam is called "killing pigs" because criminals treat the victims as pigs. At first, they would not directly ask the victim for money, but first cultivate feelings with the victim and gain the trust of the victim. After the victim put down his guard, he defrauded the victim of money through investment or transfer. Especially remind single women that sometimes at the other end of the network, there may be more than one person but a gang to deal with themselves.
Second, don't trust your online friends. Because of the rapid development of the Internet, many people don't have many friends in their lives, but they can make friends online without any scruples. But making friends online is risky, because you don't know each other at all, and it is difficult to confirm each other's identity, so it is difficult to defend your rights even if you are cheated. So don't trust online dating easily. If you want to find someone online, you must choose a regular dating website.
Third, be more cautious about property. You must remember to be vigilant when making friends online. You can't trust anyone who posts it backwards. There is no such thing as pie falling from the sky. If there is, it must be a liar. Can't trust the investment of netizens. In short, you should strengthen your own prevention to avoid being cheated by swindlers.
