In a bid to aid the Pakistan Telecommunication Authority (PTA) in its ongoing efforts to block online porn in Pakistan, fifteen-year-old Ghazi Muhammad Abdullah has compiled and sent forward a list of 780,000 adult websites which he thinks should be blocked in Pakistan. Speaking to ProPakistani , Abdullah said that he sent this list to the PTA following a letter sent to him by Director General, Law and Regulations, which stated:“If there is any specific website that you wish to bring into the knowledge of PTA, it is requested that PTA may be informed of the same accordingly for further necessary action at our end.”The teenager had previously written letters to the PTA , Ministry of Information Technology and Chief Justice of Pakistan to get adult websites blocked in Pakistan.Without revealing the specific selection process for the adult sites added to the list, Abdullah told ProPakistani that he was aided by his friends whose names he wished not to share.In an ongoing clampdown on the internet, the judiciary and PTA have taken action against porn websites by blocking or banning access to over 13,000 sites in the country.Additionally, a government department has recently called for proposals for the development, deployment and operation of a national level URL Filtering and Blocking System The ad had been placed in local papers by National ICT R&D Fund, a division of the Ministry of Information Technology, on February 22, 2012. The proposal request states that each box of the system “should be able to handle a block list of up to 50 million URLs with a processing delay of not more than 1 millisecond.”
