Chiranuch Premchaiporn, the editor of the popular Prachatai news website, denied allegations that she did not remove 10 online posts perceived as critical to the monarchy quickly enough in 2008.
She told the Bangkok Criminal Court that she “immediately” blocked any comments flagged as “improper” by the Information and Communication Technology Ministry.
Ms Chiranuch described a sharp increase in online activity in the wake of a 2006 military coup that sparked five years of political turmoil in the country.
“Various comments were posted on our web board which reflected the political situation at that time. They were intensely political and there were stronger opinions which opposed the coup,” she said.
Ms Chiranuch said up to 30,000 users a day visited the Prachatai web forum between 2007 and 2008, more than 10 times previous levels.
Ms Chiranuch, who faces a second trial under controversial royal insult and computer laws, said the site voluntarily removed about three per cent of all posts during this time.
The Internet forum was closed in July 2010 amid concerns over a crackdown on commentators following deadly anti-government “Red Shirt” street protests in Bangkok.
Thailand has drawn flak from rights groups for suppressing freedom of speech using the Computer Crimes Act and lèse majesté legislation, which bans criticism of the King, Queen, heir or regent. --AFP
