She took a harmless selfie. She never expected for it to be on a porn site

An Australian woman is calling for a crackdown on porn websites after a number of photos were stolen from her Facebook account and used without her permission.

Noelle Martin was just 17 when the images were taken from her profile and shared on porn sites around the world.

In a trend known as ‘parasite’ porn, users are known to steal innocent photos of women and then make explicit comments about them after posting them online.

As well as that, users also photoshopped Noelle's head onto the bodies of porn stars, something known as ‘morph’ porn.

Noelle explained that she first made the awful discovery while using reverse Google image search with an innocent selfie of hers.

After discovering where her photos had ended up, she explained toABC News:

They were saying things like 'the amount of come that's been spilled over her could fill a swimming pool'. Or, 'cover her face and we'd f*** her body'. I was called trash, a slut.

She added:

They can ruin a girl's life by this. They literally can ruin a girl's life by what they're doing.

Noelle was 18 when she first found out and, now aged 22, she is still fighting to have her pictures taken down.

But it's been tough - she says while police have been sympathetic, they have simply referred her from one department to another.

One webmaster apparently blackmailed her, asking for nude photos for his personal collection in exchange for their removal.

The law student has since joined up with other ‘parasite porn’ victims to campaign for stricter, clearer laws to protect future victims.

Asked if she had a message to those who stole her photos, she said:

This needs to stop we need to send a message that men and these perverts can't abuse and violate women like this.
