In 2009, when she made her case public, after 9 years of being kidnapped, tortured, and sexually assaulted, she created the campaign "No Es Hora De Callar" campaign (Now is not the time to remain silent), that managed to raise awareness on gender violence among victims like her.

In 2013, she ranked among the top 100 most influential journalists covering wars and violence.

She was part of the group of victims that participated in the peace negotiation between the government of Colombia and the FARC guerrillas in Havana, Cuba. Her involvement and work in these negotiations made it possible for sexual violence to be incorporated into the agreements as a penalty crime, not subject to pardon.

She is currently leading the regional initiative #MyVoiceAccount to decry the commercial sexual exploitation of children and teenagers.
