Defence counsel John Westgate argued his client's threats in the most recent case were "flow of consciousness", lacked specificity and he said there was never any intent they would be carried out.
He also submitted Judge Phillips failed to properly recognise Laing's Asperger's Syndrome.
While the judge discounted the sentence taking it into account, Mr Westgate said other similar cases had resulted in greater cuts.
The court at sentencing heard the victim faced a three-month barrage of calls and messages from Laing.
"I don't need to be a stalker I don't need to contact you I need to kill you," said one.
"My feelings are to murder you and I will enjoy it because I don't like you I'm going to get you for what you've done."
When the family blocked Laing's social media accounts, she simply established new ones under false names.
She also targeted the victim's mother, sending her 13 messages on Facebook featuring similar aggressive rants after being interviewed by police.
A psychologist's report before the court revealed Laing acknowledged she was desperate to find someone who would love and cherish her.
"When that does not happen, she becomes very angry and behaves in a way that causes people distress," it said.
Justice Nation said counselling was ongoing behind bars and was focused on Laing's need "to recognise the harm and distress she causes, accept she is responsible for her actions, and not blame others or the justice system for the situation she is now in".
Crown prosecutor Chris Bernhardt conceded Judge Phillips' approach to sentencing was "unconventional" but stressed the end point was not manifestly excessive.
The judge agreed. The sentence could have been as high as two and a-half years' imprisonment.
