When Mr A saw the ex in person, the ex fractured Mr A's eye socket. He was later charged and found guilty for assault accessioning actual bodily harm.
Following the altercation, the ex uploaded the couple's home made porn to YouTube and sent links and images to Mr A's mother and family.
At 2.30am the next morning, while Mr A was in casualty with the fractured eye socket, the ex emailed Mr A's boss and colleagues images and a copy of the Youtube link comprising the home made porn.
The ex also published Mr A's phone number and address to online dating sites and requested people unknown to Mr A to visit.
"While the images were taken down off Facebook mostly within a few hours, the email to my work was not able to be retracted," Mr A said.
"The damage by then was done. In one way it's good because there's nothing hidden about me any more, but on the same token, my job, my ability to perform, has nothing to do with who I sleep with. I wasn't hired because of who I sleep with, I was hired because of what I do, and it makes it difficult."
Mr A said he couldn't pinpoint a reason why the ex-lover had committed such an act, saying "no explanation rationalises it or makes sense of it".
"This isn't high school revenge. I went to bed every night not wanting to wake up the next morning. I just didn't want to deal with it."
Despite the group email, Mr A's work and boss were remarkably supportive, replying 'this says nothing about Mr A and everything about you'.
Colleagues were counselled and Mr A retained his job. "Their response was amazingly good, you couldn't want for better," Mr A said.
It comes as the Office of the eSafety Commissioner warns that online crime is a "global phenomenon".
A 2015 report found 10 per cent of Australians reported that someone had posted online or sent onto others a nude or semi-nude image of them without their permission.
Last month, news.com.au exposed a number of vile blogs that were publishing photos of Aussies without their knowledge while they were naked, at the gym or in a public toilet.
The blogs, hosted by social networking site Tumblr, contain pictures of men in major cities including Sydney and Melbourne who have been filmed without their knowledge.
