South by Southwest Interactive announced Monday it had canceled two panels at the Austin-based media festival related to gaming and online harassment after receiving "numerous threats of on-site violence."

Members of the "Level Up: Overcoming Harassment in Games" panel said they had received emails on Monday notifying them that SXSW had canceled the discussions after receiving threats.

While the Level Up panel was not specifically about Gamergate, a movement known for harassment of women in the online gaming community, it was filled with women panelists who had previously been targets of harassment, including Randi Lee Harper, Caroline Sinders, and Katherine Cross.

The other canceled panel, "SavePoint: A Discussion on the Gaming Community," included Perry Jones, Mercedes Carrera, Nick Robalik, and Lynn Walsh, who had been previously involved with the Gamergate movement.

"We had hoped that hosting these two discussions in March 2016 in Austin would lead to a valuable exchange of ideas on this very important topic," SXSW Interactives Director Hugh Forrest said in a statement Monday. "However, in the seven days since announcing these two sessions, SXSW has received numerous threats of on-site violence related to this programming."

"SXSW prides itself on being a big tent and a marketplace of diverse people and diverse ideas," Forrest said. "However, preserving the sanctity of the big tent at SXSW Interactive necessitates that we keep the dialogue civil and respectful. If people can not agree, disagree and embrace new ways of thinking in a safe and secure place that is free of online and offline harassment, then this marketplace of ideas is inevitably compromised."
