Shanghai to harass illegal advertisers

China’s largest city plans to hound people sticking up illegal flyers with new software that repeatedly calls numbers placed on the ads, an official newspaper reported Friday.

The computer phone harassment is the latest tactic in the battle to curb unsightly ads that festoon walls, lampposts, phone booths and virtually every other public surface in the city.

Numbers will be called every two hours over the first two days with a message ordering the person whose phone it is to appear to pay a fine and remove the ads, the Shanghai Daily said.
