NEW DELHI | BENGALURU: The government has sent a notice to internet service providers to block more than 850 porn websites. The order was sent late on Friday and service providers have already started blocking popular porn sites like Pornhub and Brazzers.“The telecom department sent an order to block 857 websites late on Friday. That is probably why only few ISPs have blocked these over the weekend,” said a source familiar with the matter. The government had earlier asked the Internet and Mobile Association of India to prepare a list of porn sites that can be blocked. ET was the first to report on the government's move in November.Two top internet company executives said the industry was not completely willing to help the government to block porn until it comes up with clearer definitions around what can be blocked and what cannot. “After the government meeting, there was an internal meeting of Internet companies and we haven’t moved from our side,” said one of the executives requesting anonymity. “What’s nudity to one person might be art to someone else. The scope of what can be blocked has to be really narrow,” he said. Rakesh Garg, secretary at the department of telecom, could not immediately be reached for comment.Internet companies were asked to prepare the list after a meeting in last September, chaired by telecom and IT minister Ravi Shankar Prasad and attended by top officials. It discussed the “problem of porn” and the minister directed the departments of IT and telecom to work together to improve “blocking infrastructure” at the ISP level. The meeting of the Cyber Regulation Advisory Committee was triggered by a directive from the Supreme Court, which is hearing a petition by a lawyer seeking to ban porn as it leads to “activities like rape, harassment, molestations of women”. The matter came up before a bench headed by the Chief Justice on July 8.The court agreed with the seriousness of the matter, according to the Centre for Communication Governance, National Law University Delhi, and agreed to look at the issue of “revenge porn”. However, the Chief Justice refused to pass any interim order and stated that the court cannot interfere in what adults do inside the four walls of their house.Banning porn is not easy as there are thousands of websites hosted abroad and serve porn to consumers in India.(Additional reporting by Gulveen Aulakh)
