Ingram, an Internet technology company that provides word-of-mouth services for enterprises, claims to create a closed-loop private domain traffic pool for branding, search, and word-of-mouth for enterprises.

　　The person in charge of the company told reporters that many of the questions and answers that netizens saw when they asked for help in Q&A, encyclopedia, forums, etc. were made by word-of-mouth companies like them who pretended to be real users and made "self-questioning and self-answering".

For example, in a set of questions and answers about Metaverse concept products, one of the questions involved Metaverse virtual real estate investment. The answer said that investment in virtual real estate was hot, and that he invested in virtual real estate on a company platform.

"From the perspective of a third party, tell everyone that investing in this can make money." In addition to hiring navy soldiers to pretend to be real users and mislead netizens by asking and answering questions, the word-of-mouth marketing company also has a technology called "Wanciba Screen", which can be used by tens of thousands of people. The setting of a large number of keywords allows users to always rank in the front of the promoted company when searching.

　　The reporter saw in the backstage of the system of Shanghai Top Craftsman Company that they made a Wanciba screen for an international school.

When parents search for brand campuses, reliable primary schools, and reliable campuses, this international school will rank at the top.

For critical reports and user complaints published by some users, word-of-mouth marketing companies will also use technical means to directly display web pages as 404 pages with no content found.

Ingram's business manager specially showed the public opinion purification contract they signed with a certain company. After completing the contract, the work summary showed that Ingram 404 processed a number of negative news involving the company's arrears of wages and other negative news.

"The content of the complaint itself actually exists, but we blocked it with 404."
