"Short video ads are like psoriasis. You just clicked 'close ads' on your front foot, and you can brush them again in a few minutes." Mr. Wang, a software development engineer, often brushes microblog short videos on the subway after work, but he is always disturbed by advertisements. Nowadays, short video apps are becoming more and more popular. When watching short videos, most people don't want to be disturbed by advertisements, but after many times of choosing to close, the platform will still recommend the same advertisement to users. "I don't know how many times I've brushed the advertisement of '0 yuan astrology class'. It's said that through constellation analysis and astrology, I can achieve a double harvest of career and love. I don't believe this. I feel disturbed every time I see it." Mr. Wang said. In order to avoid being disturbed, he clicked the "close advertisement" button several times and chose "don't see this video again". However, before long, he will brush the same advertisement again. Mr. Wang's experience is not alone. User pan also said that the setting of closing advertising is useless. "I have tried to close, report and complain, but I still often brush the same advertisement. I feel that closing advertising function is like a 'placebo', which has no substantive effect." The reporter tested the closing advertising function of microblog short video. On January 3, the reporter conducted the operation of "no longer see this video" on an astrology class advertisement; On January 4, when the reporter brushed the short video again, he still saw the video. Also on the morning of January 4, the reporter "didn't want to see the author's video" for an eloquence training course advertisement. In the afternoon, the reporter still received the recommendation of the platform for the same author's advertising video. The reporter learned that in the future, advertising on Internet platforms such as psoriasis will be regulated. Article 23 of the data security management measures (Draft for comments) stipulates that when network operators use user data and algorithms to push news information and commercial advertisements (hereinafter referred to as "targeted push"), they shall clearly mark the word "targeted push" to provide users with the function of stopping receiving targeted push information; When users choose to stop receiving directional push information, they should stop pushing and delete the collected user data and personal information such as device identification code.
