The "brush class platform" profited from it, boasting that 45 yuan "completed the course" and 100 yuan "passed the final exam", which encouraged "not learning" and "spending money to buy points", which not only wasted high-quality teaching resources, but also made some people with weak self-control neglect their studies, which was more likely to cause new unfairness. Students' "brushing classes" reflects the irresponsibility of some university teachers. They throw online classroom tasks to students without screening. As long as it's time to watch, they think the students have learned well. This teaching mode itself is not desirable.

Millions of college students' bad style of "spending money to brush classes" and "unable to learn" cannot grow. For developers who seek illegitimate interests, they should be severely cracked down according to law to make an example. Of course, students who spend money on online courses need profound reflection and education guidance, but they can't hit all the sticks on students.

The industrial chain of "paying for brushing classes" is numerous and covers a wide range, exposing huge loopholes in the online education platform. On the one hand, relevant platforms need to make up for technical loopholes, and the assessment of online courses should also be changed from technical standards such as online duration to content-based standards, so as to prevent online courses from "learning" from the source.

Technology is a double-edged sword. While enjoying convenience, we should also be alert to the hidden dangers. Especially in the field of education, because of its huge audience and huge profit space, it has always been the outlet of technological development. Therefore, once there is a slight loophole in control, chaos will breed. An example is that the brushing platform invades a large number of open online courses, all kinds of image search software are alienated into "copying homework artifacts", and homework punching apps are implanted with inappropriate information for children, and so on.
