Female nurse, 27, posed as male doctor in order to get women patients to send her explicit pictures of themselves.
Adele Rennie, 27, used a host of aliases and a voice-changing app to mask her true identity while trawling social media sites to find victims for her ruse.
Rennie, a former staff nurse at Crosshouse Hospital in Ayrshire also pretended close relatives were dying so that she could gain sympathy.
She has now admitted 18 separate charges of stalking causing fear and alarm, sexual offences, data protection breaches, attempting to pervert justice and breaching bail conditions between 2012 and 2016.
Kilmarnock Sheriff Court was told how Rennie made a friend request to a 22-year-old woman on Facebook, telling her she was a doctor called David Crolla.
Exactly two years later she sent the same woman another message saying she was Dr David Graham, who lived in Newton Mearns, Glasgow and whose mother had died of cancer.
Prosecutor Scott Toal told the court that Rennie phoned the victim, who “noticed she had a strange voice”.
