A man posted pictures of his son’s former partner on pornographic websites and invited men around to her home for sex.
Former soldier Stuart Marshall, 53, took pictures from the Facebook page of Lisa Frank and doctored them to show her engaged in sexual activity with other men.
Pictures of her home and her address were also published on the internet and Marshall swapped e-mails with other men posing as the mum-of-two, Leeds Crown Court heard.
He also exchanged messages describing vile acts of sexual violence and rape.
Marshall, of Pembroke Towers, Gipton, was jailed for nine months yesterday after pleading guilty to harassment.
Allan Armbrister, prosecuting, said Miss Franks, 30, only became aware of what Marshall was doing when she received an anonymous Facebook message saying she had appeared on the sexually-explicit sites.
Mr Armbrister said Marshall’s actions had left Ms Franks disgusted and in fear for the safety of herself and her children as a result of personal details being made public.
Marshall’s campaign lasted for two months until Miss Franks became aware of what was happening and notified police in December 2010.
Sohail Khan, for Marshall, said the offences occurred at a time when he was experiencing problems with his partner and he was drinking too much.
He said: “It began when he was sitting at his computer when he was drunk, sexually frustrated and one thing led to another. It is only by the grace of God that Lisa Frank’s was not contacted in person.”
Mr Khan said Marshall worked as an ambulance driver at St James’s Hospital. He had previously spent six years in the army as a bombardier and had been a machinist at a firm in Leeds.
Jailing him, Judge Geoffrey Marson QC said only a jail sentence was appropriate. He added: “This was no spur of the moment offence. It occurred over a prolonged period of time.”
