A Muslim convert who ran a hate campaign against the creators of South Park has pleaded guilty to communicating threats.
Jesse Curtis Morton, also known as Younus Abdullah Mohammad, was charged with communicating threats in 2011.
Mohammad pleaded guilty in a Virginia court to conspiracy, communicating threats and using the internet to intimidate after the threats were made on his website. He will be sentenced at a later date.
Defending, James Hundley said that each count carried a maximum of five years' imprisonment.
Mohammad's website partner on the website, Zachary Chesser, was sentenced last year to 25 years in prison.
The website took offence when South Park creators Matt Stone and Trey Parker made an episode that "defamed" the prophet Muhammad.
Chesser twice attempted to travel to Somalia to join the terrorist group al-Shabaab, once taking his infant child with him to look less suspicious.
Hundley said that his client was engaging in freedom of speech but ultimately his client wished to plead guilty.
"Is this free speech or speech that crosses the line into criminal conduct?" he said.
