What happens to a person's social media accounts after their death is one of the vexed issues of the internet era.
"[Death] is one of the least well thought-through things about social media," Tama Leaver, senior lecturer at Curtin University's Department of Internet Studies, told 720 ABC Perth.
"There's all this excitement about getting on board and talking to each other, but what we do with the stuff that is left behind is something that they [social media users] have had to retrospectively figure out."
The problem is most acute for the world's biggest social network Facebook, which is now over 10 years old and has more than 1.5 billion active users.
Facebook has now introduced the option to add a legacy contact to your profile but few people are aware of it, according to Dr Leaver.
"It is a limited function, it doesn't mean that you get control of someone's account, it only means you can post a message after they pass away," he said.
"They can't go back and edit or delete stuff."
Once the legacy contact posts a final message, the profile is then memorialised by Facebook.
Digital shrines created
No new friends can be added but people can post messages of remembrance to the page.
"Often memorialised pages become digital shrines and on the anniversary of someone's death or their birthday people post messages," Dr Leaver said.
