For the past month local magazines had one thing in common - half-naked women wearing G-strings or lacy underwear on their covers. However, last week publications such as Next, Easyfinder, Sudden Weekly, Oriental Sunday Magazine and East Week suddenly pulled the near-pornographic images off their covers, at least for the meantime. The move followed a protest by the Anti-Pornographic and Violent Media Campaign outside the headquarters of Next Media, New Media Group and Sing Tao News Corporation. Lam Keung, a spokesman for the campaign, welcomed the change but was worried the cleanup was no more than a knee-jerk reaction. 'They are very sneaky. It is just an instant reaction to a direct threat. If you don't monitor what they are doing closely they will slip back. These short-term changes happened in the past too but they always regress.' The coalition of 17 groups has called for a public boycott of Chinese-language newspapers and magazines over 'sleazy' content. Oriental Sunday Magazine refused to comment. New Media Group, Sing Tao News and Next Media did not return calls. However, East Week magazine offered some insight into its standpoint last week. In a gossip piece about Taiwanese actress Joey Choi Wai-man - whose nude photos were on magazine covers in the past two weeks - they shifted the blame. 'Recently she has been parading her sexy image to do cover photo shoots ... Last Saturday her actions finally prompted a protest by a dozen people from the Professional Teachers Union, who said that she was a bad influence on kids and immoral,' the article read. Jess Chan Yin-ping, a representative of the Society for Truth and Light, hit back at the magazine by saying: 'We studied the covers and contents of these publications from April to June. So our protest was not targeting a single person or event. Besides, on October 19, East Week ran a story about a different female star who was wearing a T-back.' Accusing East Week of a 'bad attitude', Mr Lam said: 'The words are theirs and they hold all the power to write what they want. They don't seem to have any intention of improving their ethics.'
