A former BBC radio presenter found guilty of stalking four people including broadcaster Jeremy Vine has been jailed for five and a half years
Mr Justice Saini, told Belfield. "You made this highly successful and confident radio presenter lose all joy in life and turned him into a shell."
The judge said that while Belfield did not physically approach or watch his victims, the effects were just as damaging.
The judge said he agreed with some of the witnesses in the case, who said Belfield had "weaponised the internet".
The judge said it was an aggravating factor that Belfield's harassment was public, as this caused his social media followers to also abuse Mr Spedding over a "lengthy period".
The judge said Belfield had made "wholly false" allegations about Mr Vine stealing £1,000 of BBC licence payers' money, in a video which was viewed by more than 400,000 people.
The judge told Belfield he will serve up to half of his sentence in prison and the remainder on licence. He warned him he could then be recalled to prison if he commits a further offence.
