Recently, multiple netizens in Guangzhou reported that the Guangzhou Metro app's ride-hailing code function frequently displays pop-up advertisements, particularly when using the 'shake to pay' method, which severely affects the efficiency of peak hour boarding. In response, Guangzhou Metro's customer service stated that 'not everyone dislikes watching ads,' and that passengers with related complaints can provide information for the technical department to handle. However, a staff member from the Guangzhou Municipal Market Supervision and Administration Bureau pointed out that the Advertising Law clearly stipulates that pop-up ads must have a prominent close button and be easily closable, with violators facing fines of 5,000 to 30,000 yuan. The controversy has sparked heated discussions among netizens, with some calling for the removal of advertisements from the app, while others argue that they are a necessary source of revenue for the metro system.
