Digital travel scams are a growing "systemic and global" problem, according to the World Travel Organisation, a branch of the UN.
Dozens of Brazilian women have been finding this out the hard way, after paying for luxury holidays from a man whose Instagram account sparkles with opulent hotels and exotic locations.
Travel agent Rafael Bessa has been accused by dozens of people of holiday scams leaving them with losses of thousands of dollars.
"I was in hell. I had never faced a worse situation in my life, I never had anything worse in my life than those seven days in Greece,” one woman said of her experience.
Rafael Bessa declined an invitation to interview and denied all allegations.
