Bristol Palin's stalker has been sentenced -- yet again -- for harassing the famous Alaskan family, and now he's been ordered to spend time behind bars.
Peter Ferrero just got slapped with 30 days in jail after violating his probation and harassing the Palin family.
The judge also ordered Ferrero to pay a fine and have no contact with Bristol and Dakota Meyer, as well as the other Palin sisters, Willow and Piper.
As we previously reported, Ferrero had been contacting the girls on social media, and even made threatening sexual messages towards 16-year-old Piper. He was arrested in July after exposing himself and attempting to urinate onto oncoming traffic.
Sarah Palin's other daughter, Willow, also filed a restraining against Ferrero claiming she thought he may try and kill her family.
He remains in custody.
