[Algorithm mechanism disorder, Douyin suddenly experienced large-scale service abnormality] September 1st, from the evening of August 31st to September 1st, Douyin platform suddenly experienced large-scale service abnormality, causing the recommendation algorithm to become chaotic. A large number of users were forced to push non-daily attention content on their homepages, causing netizens to complain that "Douyin recommendations are ugly." The specific manifestations are that the recommendation algorithm is disordered, users' daily preference tags are invalid, and non-daily attention content is pushed on the homepage; a large number of users report that clicking "not interested" or swiping quickly still cannot prevent similar low-quality content from continuing to flood the screen; basic functions are partially paralyzed. In addition to abnormal recommendation flow, some users experience blank search pages and the inability to send and receive private messages. As of press time, Douyin has not responded yet.
