It seems that there are a few similarities in the rules of rhetoric for writing in GP and political propaganda in Singapore. In this (free) article on the Straits Times Interactive, Minister for Information, Communications and the Arts Lee Boon Yang explains why the streaming of explicit political content through podcasts or videocasts is not allowed but posting of party manifesto and texts of rally speeches allowed for political parties.
Election advertising on the Internet has been permitted since the 2001 polls, and remains restricted only to political parties, candidates and election agents. As for bloggers who 'dabble in political content' (see this subscription page), if the Media Development Authority finds them to be 'promoting a certain political line', they will be told to register with the MDA and suspend their online political advertising.
Perhaps the more interesting ban is the one on podcasts or videocasts containing content such as election rallies or views on the polls, in view of the allowance for political parties to post party manifesto and texts of rally speeches. The minister cited the greater persuasive power of podcasts and videocast when compared with written texts and likens them to party political films and videos, which are also disallowed. He mentioned Fahrenheit 9/11 as an example of 'slanted propaganda' that selects images and quotes politicians out of context to achieve an emotional response.
The characteristics of the Internet that the incumbent party finds most worrying are its ubiquity, speed and anonymity. The minister referred to the incident in which the spurious statement that Zaqy Mohamad, a new PAP candidates, was a nephew of Speaker of Parliament Abdullah Tarmugi and the speed with which this untruth spread through the Internet. While he conceded that this piece of misinformation was not particularly significant, the minister pointed to the volatile issues of race, language and religion, which provides the government with justification to use the MDA to promote accountability on the Internet.
Also worthy of note are the rules governing the role of foreign media in local elections. No foreign news organisations operating in Singapore are allowed to involve themselves in domestic politics here. 'Singapore politics is for Singaporeans only'.
I'll end off here with a quote that the Straits Times selected from the email interview:
I agree that the controls are not water-tight. The virtual nature of the Internet and its global scale make regulation difficult. But rules do have some effect. They set a certain standard and help maintain order and accountability in the way political issues are discussed over the Internet.
