Greg Bruce, who maintains the website www.leithnd.com, told the news service that a Grant County sheriff's deputy served him with a temporary restraining order Wednesday.
The order bars Bruce from having contact with Deborah Henderson, except through an attorney, and prevents him from saying anything "slanderous, harassing or threatening" about Henderson or her family on his or any other website.
Henderson's boyfriend, Kynan Dutton, was arrested and jailed along with the leader of Leith's white supremacist movement, Craig Cobb, for allegedly threatening neighbors with guns.
Henderson told the Forum News Service that Bruce was "harassing me to the point where me and my children don’t feel safe," pointing to a sidebar on the website's homepage that links to a report for suspected child abuse she believes was directed at her family.
For his part, Bruce argued he's never slandered Henderson, though he told Forum News Service he has "come close."
Cobb was also a target of apparent harassment: shortly after a DNA test revealed on daytime television that he was genetically "14 percent sub-Saharan African," his home was tagged with racist graffiti.
