He was responding to questions about the Indonesian government's decision to block all access to Telegram, following revelations that several forums hosted on the application were "full of radical and terrorist propaganda". Indonesians are among the world's biggest users of social media.
While Indonesian IS militant Bahrun Naim, has been known to use Telegram to contact Indonesians from Syria, Ms Nuraniyah said the majority of people linked to extremist groups used the application for gossip rather than terrorist plots.
Ahmad Zahid said the government also had some decoding methods to monitor methods used by Daesh for dissemination of its ideology, recruiting members and obtaining funds via social media or online communication platforms.
"Telegram is heavily encrypted and privacy-oriented, but we're no friends of terrorists", Mr Durov said on his Telegram channel, adding he was "upset" over Indonesia's ban.
In his Telegram channel, Durov made an official statement saying he regrets failing to provide a quick response to the Indonesian Communication and Information Technoligy Ministry's request to regulate contents of terrorism in the app's public channels.
Pangerapan told the Jakarta Post Telegram did not have a standard operating procedure (SOP) for the handling terrorism-related content.

However, as outlined in its code of conduct, the ICT Ministry can not request a ban or block on any web portal, but instead only processes requests from other government institutions.
The ministry warned that it would block Telegram if the company behind it did not filter what it called "illegal content".
Indonesia said it will block the app if it continues to be a platform for radical propaganda and violent militants.
Infiltration, she said, was more "realistic and urgent" and the government should aim to identify and map out ISIS networks on Telegram.
Durov said Telegram blocks thousands of IS-related channels a month and is "always open to ideas on how to get better at this".
The free messaging service can be used as a smartphone app and on computers through a web interface or desktop messenger.
Indonesia has faced several terror attacks over the past year.
