A day after the Delhi police booked Twitter for allowing access to child porn, the microblogging platform has said it has a "zero tolerance policy for child sexual exploitation" and has developed special special tools to detect and remove content linked to child pornography and the accounts linked to it.

According to a report by ndtv.com, Twitter said that "viewing, sharing, or linking to child sexual exploitation (CSE) material, regardless of the intent, contributes to the re-victimization of the depicted children and is prohibited on our service".

The Delhi Police has sent a notice to micro-blogging site Twitter seeking details about steps taken by it against circulation of child pornographic content on its platform following the FIR.

The police have sought to know the steps taken by Twitter officials concerned against child sexual abuse content on their platform and sought details of the accounts circulating such material.

A spokesperson of Twitter on Wednesday was quoted by ndtv,com, saying that in 2019, the platform launched a feature in search prompt aimed at deterrence of child sexual exploitation.

"The prompt was developed in collaboration with the Ministry of Home Affairs and NGOs in India to blacklist specific CSE search keywords in Hindi, English, Bengali and Kannada," the spokesperson was quoted as saying.

"We have been at the forefront of responding to the evolving challenge of preventing the exploitation of children on the Internet and will continue to aggressively fight online child sexual abuse, as well as invest in the technology and tools that are essential to stay ahead of this issue,"Twitter said.

"We will continue to invest in proactive detection and removal of content that violates the Twitter Rules and work with law enforcement and NGO partners in India to tackle the issue," the spokesperson added.

The Delhi Police had registered an FIR against Twitter for allegedly allowing access to child pornography on its platform following a complaint by the National Commission for Protection of Child Rights (NCPCR).

The case was registered under relevant provisions of the Indian Penal Code (IPC), Protection of Children from Sexual Offences (POCSO) Act and the IT Act, police said.

This comes days after the NCPCR, the country's apex child rights body, asked Deputy Commissioner of Police (Cyber Cell) Anyesh Roy to explain why no action had been taken against Twitter as per its letter to the Delhi Police dated May 29.

In its letter, the NCPCR had asked the Delhi Police to book Twitter on the basis of the findings of its recent inquiry in which it had found that child sexual abuse material (CSAM) was easily available on the platform.
