A student who participated in a vile Year 12 muck-up day scavenger hunt tormenting a sexual abuse survivor was not allowed to graduate with his class after the school learned of the prank.
Leaving students at Merewether High School in Newcastle, north of Sydney, were challenged to send the girl - who was abused from the age of four to 10 - a message 'defending paedophiles' to score points in the hunt.
One of the boys who participated messaged her late on Wednesday night to say: 'I really don't think paedophiles are that bad.'
When she questioned the message, the boy added: 'My uncle was one and I think he's a good bloke. Is there anything wrong with that?
'Everyone is human. We are all the same, black, white, pedo, not pedo.'
But just days later, the student changed his tune and sent a grovelling apology to the young girl, insisting that he didn't understand the gravity of the situation.
'I'm young and stupid,' he confessed. 'None of this was meant to hurt anyone.'
The boy said he thought he was participating in a harmless challenge, and said he had no idea of the young woman's traumatic personal experience.

'I thought it was a simple scav task. I had no idea of the unimaginable consequences of my actions,' he wrote.
'It makes me sick thinking about what I have done.'
The New South Wales Department of Education told Daily Mail Australia he was barred from graduating with his peers after the school learned of the incident.
'A student who taunted a sexual assault survivor online was barred from the final Year 12 departure ceremony,' a spokesman said.
He added that the student would face further disciplinary action.
He went on to say the overwhelming majority of the cohort understood not to participate in scavenger hunt challenges and that it violated campus expectations.
'Year 12 students at Merewether High School have a very clear understanding of the high standards expected of them by the school in relation to their final days of schooling,' he said.
'The posts setting up the ''hunt'' were not from a student or students enrolled at Merewether High School, and the school referred the matter to police.'
In a sickening abuse of trust, the challenge was actually created by a former student who graduated from the same school in 2019 and was a friend of the victim.

She had recently confided in him about being sexually abused by a close family friend over six years.
Daily Mail Australia understands he has since been fired from his job after his employer learned of the prank.
The mother of one of the boys was 'horrified' when the school informed her that her son had participated in the degrading activity.
In Facebook messages obtained by Daily Mail Australia, graduating students contacted the vulnerable teenager - who does not even go to the school - late last Wednesday night to defend paedophiles in a sick attempt to elicit a reaction.
The young woman, who can't be identified, later learned the messages were sent to earn points for the selective school's muck-up day scavenger hunt.
Other challenges in the warped hunt included flicking a dog's testicles, abusing a teacher via email, filming sex acts and abusing new mothers.
It is the latest in a string of sick muck-up day challenges involving graduating NSW students, including at elite schools such as Shore in Sydney where so-called pranks included spitting on homeless people and defecating in public.
The girl's shattered mother told Daily Mail Australia the messages had 'broken' the 18-year-old, who recently started university after leaving school in Year 10 to cope with her trauma.
'The days of throwing toilet paper over lawns and having innocent fun are gone... This is way too far,' the mother-of-three said.

The messages immediately triggered the young woman, who was repeatedly molested as a child and has needed therapy to deal with her trauma ever since.
A friend in the year group revealed he saw the muck-up day challenges for Year 12 students, and the messages were part of the twisted game to earn notoriety and points ahead of graduation.
The boy who created the challenge, she confided in him. She thought he was her friend and instead he's turned her trauma into a joke
'She was sobbing, shaking,' her mother tearfully explained to Daily Mail Australia late on Wednesday night.
'She feels so humiliated and exposed.'
The exact challenge was for the students to 'message [her] and start an argument about paedophilia', all while knowing about her traumatic experience.
'The boy who created the challenge, she confided in him. She thought he was her friend and instead he's turned her trauma into a joke.
'We're just totally shattered, and that's an understatement.'
On Wednesday night, the young woman decided to confront the issue on Facebook after she realised 'all of Newcastle was about to find out about it one way or another'.
'I thought it would be better for it to come from me. It was my story to tell and I wanted to be able to tell it myself rather
