As reported by Forbes, New York Times writer Tariro Mzezewa also tweeted that she spoke to some Turkish women who said that the trend “started there as a response to them being frustrated over always seeing black-and-white photos of women who have been killed.”

Mzezewa added in additional tweets: “The Turkish hashtags about domestic violence and femicide were dropped as the challenge went viral… The original accompanying hashtags were #kadınaşiddetehayır #istanbulsözleşmesiyaşatır which I’m told translate to say no to violence against women and enforce the Istanbul Treaty/ Doctrine (where rights to protect women are signed.)”

And others on Instagram, too, have abstained from posting their own selfies when nominated. Instead, they have shared full-colour photos of Gultekin, the 27-year-old university student whose body was found in the Aegean district of Muğla on Tuesday 21 July.

“It dawns on me that in the posting of all these beautiful pics, the picture we should all really be posting (in full colour, in my opinion) is #pinargultekin who was brutally murdered in Turkey earlier this month,” noted CEO Dija Ayodele, in a thoughtful caption accompanying her own post.
