How is the WeChat free open class marketed?

The marketing routine of WeChat free open class is as follows:

Let's drag you into the group first. It is true that some people will teach 1~2 lessons for free and talk about some basic knowledge of painting. You think you can learn this way, but you think too much.

Then the teacher will show pity, hoping that you can send it to 2~3 groups, or pull it to 2~3 groups, so that you can unlock more classes.

Then he will ask you to register some websites or download some apps in various names. Some of them need to be bound to their identities, and all the security information you think is exposed to them in plain text.

Your ID card information, mobile phone number and even bank card, some passwords (many people have the same password, so you can use your mobile phone to crash into the library, in short, automatically connect to various forums), your address book, and your photo album.

You will find that for a period of time, you often have all kinds of verification codes, all kinds of harassing calls, and you unconsciously registered some websites.

There are even common scams, and relatives receive fraudulent calls.

They have all the scams you can think of, and they will have them if you can't think of them.

Don't believe in free lunch, remember that free is always the most expensive.
