Poll: Should those who post abuse on social media be banned for life?
Sheffield United have said they are "appalled" by the abuse being aimed at people who have criticised the club's decision to allow convicted rapist Ched Evans back to training.
It follows the Twitter abuse aimed at Olympic heptathlon champion and local hero Jessica Ennis-Hill, who said that to allow Evans back into the Blades squad would "completely contradict" her beliefs of being a role model to young people.
She was taunted with several sick tweets including one saying: "I hope he (Evans) rapes her."
