So did you go surfing or not?

Is Huang Tui this competitive now? I have already blocked over 100 messages from this person today. I think we could come up with a 'spam advertisement' index in the future. I can hardly see the previous AI Huang Tui anymore. I don't understand what the profit model for Huang Tui is. How many people really follow after seeing such ads? I looked at the referrer's followers and it hasn't increased much.
