Nighat Dad, Pakistan's digital warrior battling the patriarchy.

Islamabad: But this human rights award winner and founder of Pakistan's first cyber-harassment helpline still tears up as she describes receiving calls from women afraid of being killed by male relatives for using the internet."We sometimes find ourselves helpless... Somebody calls us and asks for help while crying that 'Please, please save my life'," she tells AFP at the offices for her non-profit Digital Rights Foundation in the eastern city of Lahore.Much of Pakistani society lives under the patriarchal, outdated code of so-called "honour" that systemises the oppression of women by preventing them from, for example, choosing their own husband or working outside the homeActivists have denounced pervasive, sometimes deadly violence by men -- usually male relatives -- against women who break those taboos.The situation is dire enough in the offline world.But Pakistan is only just beginning to grapple with what violent notions of honour mean for women online, in a country where internet penetration is at 22 percent and growing, but digital literacy is low.

There have been examples of men attacking women for using the internet in ways that much of the rest of the world considers normal, such as publishing photos of themselves on a Facebook page.Women are suffering

Dad formed the Digital Rights Foundation, a think tank tackling digital rights through a gender lens, in 2012, winning her recognition as one of Time magazine's next generation leaders in 2015 and a Human Rights Tulip award in 2016. She launched the cyber-harassment helpline that same year, funding it with the 100,000 euros ($108,000) in Tulip prize money.

The idea, she says, "came out of anger" at the violence women were suffering.

The helpline now receives up to 20 calls a day and the number is increasing.

Callers range from celebrities to poor women in deeply conservative areas whose male relatives do not allow them to leave their homes. Many call about the non-consensual publication of their intimate images.

The issue can be damaging enough to women in developed countries. In Pakistan, even less severe cases can see families forbidding women from attending school or forcing them into quick marriages to save their "honour", while in the most severe it can be deadly.

Much of the work the helpline does is to explain to women what recourse they have.

Social media companies are playing ball, Dad says -- some have even agreed to establish "escalation channels" for getting content off...
