They met through Craigslist.

A handful of men who didn't know each other and who ultimately became part of a group now known as the Evil 8.

One of the ads was placed by the father of a now 14-year-old girl. In the ad he described himself as a "lonely single parent looking for friendship".

He also mentioned that he was seeking modelling opportunities for his daughter.

From there other connections were made, through internet forums, or again through Craigslist with men who all had a common love. Of depravity.

The father pleaded guilty to raping his daughter, watching as the other men did the same thing, making her wear bondage attire, filming her and drugging her. In some cases he watched the paedophiles as they molested his daughter and treated her like a "sex object".

The girl's father answered an ad that one of the men, Dawid Volmer, placed on Craigslist offering sexual massages.

Volmer went on to have sex with the man's daughter three times, which included drugging and blindfolding her, while her father sat close by.

Benjamin Simon Clarke, was sentenced to three years' jail for indecently abusing and taking naked and almost naked photographs of the girl after her father, once again, answered an online ad Clarke had placed.

The father asked him if he wanted to "do more" to his daughter and she was then abused as she lay naked on a mattress.

Mark Wesley Liggins was also charged as part of Operation Ripstop and was sentenced to more than two years behind bars in May.

He used an online forum to engage in sexual conversations and exchange nude photographs with children, but he was never charged with offences related to the girl.
Instead, he was caught in the sting because he had been in communication with the girl's father, which then led to his home being raided.

The abuse either took place in the father's own home, the homes of the men or sometimes in hotel rooms.

The appalling case has been called one of the worst ever seen in Western Australia. Details began to emerge last year when the father, aged 43, was jailed for 22.5 years in what was one of the longest terms imposed by the WA District Court.

The father is appealing his sentence in the WA Court of Appeal, claiming his jail term is manifestly excessive.

Strict suppression orders prevent news.com.au from identifying the father to protect the identity of his victim, his daughter.

Yesterday Ryan Trevor Clegg, 43, was jailed for 12 years and nine months, joining the other Evil 8 accused already behind bars.

The court heard Clegg said in an online chat that: "Sometimes I think she does like it. I'm gentle with her."

When the father was finally caught he told detectives he did have some regrets. But then he astonishingly said it had been "fun while it lasted" while admitting things "went way over the line". He told them he wanted to leave "the scene" and go back to being a normal member of society.

The abuse of his daughter took place between 2013 and 2015 and occurred after the girl was living with him after the end of her parents' marriage.

The shocking facts of the case were laid bare last year by Judge Philip Eaton, who told the father's sentencing of the disgraceful web the man created.

His actions demonstrated a "high degree of depravity and exploitation".

"You allowed strangers to treat your daughter as a sexual object and you treated her the same yourself," he said.

Prosecutor Justin Whalley said the father's actions were nothing like what a "proper parent" should be. Instead of protecting her, he said, he allowed her to be violated and exposed "to "depravity of the highest order".

In some instances, the victim was forced to dress in "bondage" gear and pose in sexually explicit ways for photographs.

Videos of the abuse were sometimes made - including of her tied to a bed, gagged, and wearing a dog collar that had the word "bitch" on it.

Judge Eaton told the man's sentencing hearing the man's actions would likely have lasting and irreparable consequences for his daughter, who was now 14, and maintained an attitude of loyalty to her father despite everything he had put her through.

The man did not pimp out his daughter for money rather for his own sexual gratification, the judge said.
