Gemma Capon, 20, falsely accused Graham Tysoe of forcing his way into her home and sexually assaulting her on the living room sofa.
Today she was sentenced to a 12-week suspended prison sentence, to the anger of the victim and his family.
Mr Tysoe said: "I hate her. I don't think she realises what she's done."
Mum Sharon, 42, added: "She should have been put inside. It was vicious and vindictive and the sentence has made a mockery out of the justice system. It sends the message that false accusers can get away with it."
Mr Tysoe, a 20-year-old pub worker, was arrested in front of work colleagues and held for 23-and-a-half hours after Capon made the allegation on June 5.
Southend Magistrates Court heard how he was subjected to intrusive forensic examinations during the investigation.
