Since SegmentFault launched its paid courses, it has been strictly controlling the quality of content. The lecturers prepare lessons carefully and answer questions for students after class, which has been widely praised. However, several SegmentFault lecturers recently reported that a large number of his pirated courses appeared in CSDN download channel.

Don’t check I don’t know, check we found – our lecturers have worked so hard paid courses spent hundreds of hours recorded, in CSDN download channels have a full screen of piracy (the evidence we have find a lawyer team), at the same time, according to their keywords recommended channel we found on his blog also has a lot of pirated content, small-scale operations, It’s hard to get off my chest.

Yesterday, AFTER I disclosed this matter in moments of friends, I received a lot of feedback from peers in the industry. We found that not only SegmentFault, but almost all of my peers and familiar lecturers’ paid contents (including but not limited to courses, books and columns) were infringed by CSDN download channel. Yesterday, We searched CSDN download channel with some keywords of the same industry, and also found that there are a large number of pirated content.

At the same time, we also received feedback from some users that there are a large number of scanned files of IT related technical books in CSDN download channel, which are undoubtedly pirated resources. The upload period began in 2016 (or earlier) and continues to this day.

Through keyword search in Google, we found that the first content accusing CSDN download channel ** “CSDN homepage encourages pirated Book download” was released in 2005. There were also a lot of discussions in Zhihu and other communities, such as “How to view CSDN making money by selling points for pirated materials uploaded by users? Why can CSDN make users pay for credits to download pirated resources from its own website? * *… Visible in the industry has caused public anger.

As one of the earliest technology communities in China, CSDN is recognized for its contribution to online communication between developers, but the existence of its download channel greatly contributes to the production of a large number of pirated and infringed content. It’s not unique, it’s persistent, it’s rampant, it’s never been solved — it represents a fundamental mechanical problem with their products.

Is CSDN officially unaware of this?

It’s just turning a blind eye — CSDN’s download channels account for more than 30 percent of the community’s traffic. Relying on piracy and infringement of other people’s quality content to obtain platform traffic, and then rely on platform traffic for advertising and other forms of cash. What is it if it’s not illegal profit making?

We can’t help but question what kind of values CSDN, known as the largest technical community in China, has.

Conniving at piracy and making illegal profits;

Ignoring user privacy — user data was leaked when user names and passwords were stored in plain text;

** even cheats customers – exaggerating website traffic and falsifying advertising data. ** Remember that gaffe last year when programmers ran out of AD code? “Blog details page PC increased AD system spawn code” written in the code comments online. The original customer’s advertising data are all brushed out? (Love advertising clients)

As a matter of fact, the technical circle is very small, and many peers may not openly criticize CSDN for face or various reasons, and some of the criticism may not solve the problem, which further encourages CSDN to condone piracy. SegmentFault as a member of the technology community, we know that community development is not easy and we have a responsibility to help our instructors protect their paid content from copyright infringement.

We have hired a professional team of lawyers to collect evidence. At the same time, we also call on peers, lecturers, book authors and developers who have been violated by CSDN download site to speak up together. Leave your voice and experience of infringement in the comments section, and jointly purify the industry environment by exposing infringement and even illegal acts.
