What is the purpose of those QQ groups that invite people to join, like or SVIP?

The salesman will advertise in the group, and then he should be a new group. He will tell you to pull people in, or kick them out of the group or something.

Generally speaking, many of these groups are advertising, saying that they are doing part-time jobs, saying that they have no principal and no age limit, and earn more than 300 yuan a day. These are all lies. It's impossible for someone to make their own money and call you.

Qq fraud note:

When contacting friends on social networking platforms, if the other party asks for help in payment, recharge, etc. On the grounds of emergency, check and confirm the identity of friends through telephone, video and other channels, not just through SMS to cooperate with the transfer.
