The court heard that Ringer used images of the other mother’s prematurely born daughter, The Telegraph reports.
"She was using the picture of the victim's baby reporting to people that the baby was premature, that she was seriously ill, struggling to pay for her treatment and funeral," Ms Walker said.
"The victim challenged the suspect and asked she stop using the images.
"It was then that [Ms Ringer] said she would find out where the victim lived and kidnap and rape her daughter."
Ringer has been sentenced to a two-year criminal behaviour order that bans her from using social media and for asking any third party for a donation other than for a registered charity. She also received a suspended jail term of 30 weeks and was ordered to pay £225 cost ($380 AUD).
Ringer was first discovered by investigators when her IP address was traced to a computer at her mother’s house.
