Secondly, scammers may use this as bait for fishing fraud. They may induce you to provide sensitive personal information, or pay an extra fee to get a so-called return visit reward.
In addition, the return visit advertisement itself may also be false. Some scammers may ask you to click on a link or download an application in the name of a return visit, but in fact these links or applications may contain viruses or Trojan horses to steal personal information or control your device.
Therefore, I suggest that you be vigilant and don't believe the scam of returning to 3 yuan easily. In online transactions, we should keep rational thinking and avoid being cheated. If in doubt, it is best to consult professionals or report to relevant departments.
