Pakistani teenager Zara Shah was targeted by a stranger while playing a computer game, drawn into a conversation that would expose her to terrifying online sexual exploitation.

Zara, whose name has been changed by AFP for safety reasons, is one of an estimated 1.5 million children in Pakistan who experienced online sexual abuse in one year, according to a report published by the UN children’s agency this month.

“We started chatting while playing an online game, and he began acting like a friend. Later, he wanted to meet and, after, started asking me for nudes,” 17-year-old Shah said.

“When I refused, he threatened to find my family online and tell them that we had been talking,” she added.

According to the UNICEF report, around 85 percent of perpetrators were known to the victims, aged between 12 and 17.

“The abuse may start with a friendly conversation, a gaming interaction, a promise of gifts, money or romance,” Daniel Kardefelt, lead author of the global UNICEF report, told AFP.

“Perpetrators may spend months building trust using information that they find on social media,” Kardefelt said.

In Muslim-majority Pakistan, 71 percent of victims did not tell anyone, according to the UNICEF report, while no child surveyed reported the abuse through formal channels — including police, helplines or social workers.

Their silence was mostly because of stigma, shame and fears over how their families or society may react.

“Around 44 percent of reported abuse was entirely online, with Snapchat and WhatsApp among the most common settings,” said Mehek Naeem, director of PAHCHAAN, a children’s rights organisation based in the eastern city of Lahore.

Girls can face heightened risks of sexual extortion in the conservative society, which can lead to restrictions on their mobility or withdrawal from school.

For Zara, the threat of being exposed to her family was enough to keep her silent.

“I could have been stopped from going to school or leaving the house altogether,” she said.

“Staying quiet felt like the better option than speaking up. But anxiety kills me every day.”

With around 74 percent of children aged 12 to 17 in Pakistan estimated by UNICEF to be internet users, concerns over online safety are growing as their access to digital platforms expands.

Echoing other policies around the world, the provincial government in Punjab this month passed a resolution to bar children under 16 from using social media.

However, it has faced opposition.

“I disagree with the ban,” said Usama Khilji, a digital rights activist.

“It will be a challenge to implement, and children can circumvent the ban through VPNs. Children have the right of freedom of expression, and a ban takes that away,” he said.

Pakistan has a legal framework addressing tech-facilitated offences against children, but “there is no implementation”, said Tahira Afrasiyab, a spokesperson for non-profit organisation Muslim Hands.

And, according to experts, there are loopholes in existing laws.
