(CNN) — "Yesterday I was killed."
So begins a Facebook post, now spreading virally, that's written from the perspective of two Argentinian female backpackers killed in Ecuador.
"I refused to be touched, and they smashed my skull with a stick," the post, written by Paraguayan student Guadalupe Acosta, goes on.
"They stabbed me and I was left to bleed to death. Like trash, they put me in a black polythene bag, wrapped with duct tape and threw me on to a beach, where hours later they found me."
Media reports say Maria Coni, 22, and Marina Menegazzo, 21, were sexually assaulted and killed in February while traveling in Ecuador. The pair were reportedly killed by two men who had offered them a place to stay.
The post written in their name has now had more than 730,000 shares over the past two weeks.
It's also sparked a social media debate over victim-blaming and women's right to safely travel alone.
The post was written to protest against those who implied that the two young women had invited trouble and their own brutal deaths through their own actions.
"But worse than death was the humiliation which came after," the post continues.
It criticizes the "useless questions" of people who blamed the women for "traveling alone."
The hashtag #viajosola, meaing "I travel alone," has since been picked up by thousands of people, mostly women, who are using it to share pictures of themselves on their solo travels, defending their right to explore the world without discrimination or harassment.
Many make the point that the victims weren't traveling alone, since they were together and were only seen as "alone" because they were unaccompanied by men.
"Here I am backpacking with my best friend, but for society I actually traveled alone."
Ecuadorian authorities have arrested two men allegedly linked to the murders.
