Not reliable. There are many names for "sideline training", many of which are not worthy of the name. The real purpose is to make a profit through "advertising drainage-students entering the group-fooling and realizing-selling classes at high prices". The courses that students buy at high prices are of poor quality, most of which are of no practical value, wasting money and time. Some students are also defrauded by criminals. By means of training institutions and platforms, the online sideline business of "easy to learn, quick to get started and easy to make money" is widely publicized. Some netizens listened to their side of the story, and only after paying money to participate did they find that the so-called earning high salary was just a lie. Even if someone has completed all the courses, there are still problems such as poor training quality and unfulfilled promised results, let alone easy implementation. Many participants are bluffing, but it is difficult to stop more people from joining.

From the netizen's point of view, some people may not find suitable jobs for the time being, so it would be good if they could find a sideline to make a living first. However, some netizens have their own jobs, but in line with the concept of "skills outweigh pressure", they feel that if they can have a part-time job outside of work, they can also broaden their income channels and increase their income. Some "treasure moms" who take care of their children at home regard engaging in online sideline business as a good way to earn extra money.

Some online training institutions and platforms have taken a fancy to these people's psychological demands, so they charge enrollment fees under the banner of "one-on-one" teaching and "hands-on" professors. By searching a number of online complaint platforms, it is found that there are hundreds of complaints against the above-mentioned institutions, most of which are "non-refundable". In addition, a large number of "students" are also facing great risks of being targeted by criminals involved in fraud.

The key and difficult point to control the trap of "online sideline training" lies in how to cut off the chain of illegal organizations or platforms using well-known network platforms for drainage, clarify the legal responsibility of drainage platforms, and compact the platform responsibility commitment mechanism. According to the relevant regulations of Internet advertising, platform operators, as Internet information service providers, have the obligation to supervise and inspect the advertising content displayed and released by their information services. For the trap advertisement of "online sideline training" with obvious fraud risk, the platform operator should also bear some user losses. To put it bluntly, the so-called "online sideline training" is likely to be one trap after another. We must be highly vigilant and don't easily fall into each other's trap.
