Bensfield had been arrested in January and was released Tuesday, having already served 93 days in jail. He was given credit for good behavior.
The young Naperville man sent threatening messages on Facebook to his ex-girlfriend, saying he would kill or do serious harm to her and her new boyfriend if she didn't resume their relationship, police told the Naperville Sun.
After several attempts at telling Bensfield to stop, the woman printed the messages and took them to police.
Bensfield, who may suffer from bipolar disorder, pleaded guilty to harassment by electronic communication device, reports the Daily Herald.
He has also been placed on 30 months of probation, must undergo counseling, and is not allowed any contact with his ex.
That includes "pokes."
