He said that false rape allegations undermined real victims of rape and had a serious effect “on the minds of the public who may be called as jurors, which may cause doubts in the mind where none should exist”.
The judge said Sharples “lured” one victim to a shop so he could be arrested in public and told another “watch what happens now” after he refused her advances.
Julia Faure Walker, representing the Attorney General, said the original sentence was not increased enough to reflect the number of victims.
She said: “This case clearly falls into the category of causing not just some distress or impact, but serious distress or impact.
“The vast majority were arrested, spent time in custody and remained under investigation for months.”
Hunter Gray, representing Sharples, said the sentence had been reduced due to Sharples’ mental health and lack of intellect – which the judge decided constituted a learning disability.
He said Sharples “accepts responsibility” but “still struggles to understand why she did what she did”.
During the original sentencing, the judge had described Sharples as a “sexual predator” who “bombarded” the men with “out of proportion” expressions of love and if they did not respond she reported them for rape.
Sharples did have consensual sex with five of the men, one in the homeless hostel where she was living, before she accused them of rape.
Her first offence, committed when she was 18, involved a false claim that a 16-year-old boy had threatened her with a knife and forced her to perform oral sex.
Sharples, who falsely claimed one victim was her boyfriend, told a psychiatrist she did not know why she stopped her offending but said it coincided with the Covid pandemic and her meeting her current partner in 2022.
