Jennifer Baing was scrolling through Facebook when she came across a photo of herself wearing revealing lingerie.

Scammers had used artificial intelligence (AI) to manipulate photos taken from the former PNG television host's social media accounts, where she has built a large following promoting traditional food and agriculture.

They then used her likeness to promote fake giveaways, asking people to send money for the chance to win.

"It's happening to everybody," Ms Baing said.

"Our photos are being abused, and our public standing is being abused by these scammers, these impersonators."

Her experience comes as Papua New Guinea prepares new laws to criminalise the malicious use of AI, including deepfakes, voice cloning and digital impersonation.

Experts say the reforms are needed, but warn legislation alone will not protect people unless communities understand how AI is being used to deceive.

Ms Baing said she had identified almost 100 Facebook accounts using her name and photos.

Some cloned her social media profile to impersonate her. Others used AI-generated images of her handing out cash to promote fake giveaways.

She said the harm went beyond damage to her reputation.

"So my personal safety is also at risk."

Ms Baing said she had repeatedly reported fake Facebook accounts using her name and photos, but they remain online.
