Online harassment is a real world problem, and you don't need to look any further than a cancelled South by Southwest Interactive panel for more reasons why. Citing "numerous threats of violence" the SXSW planning team has annulled "Level Up: Overcoming Harassment in Games" at next March's event according to an email sent to panelists that was obtained by Jezebel. What's more, the festival has cancelled a pro-GamerGate panel, dubbed "SavePoint: A Discussion on the Gaming Community," as well. An official statement from the organizers says that since announcing the two panels they've been inundated with threats of on-site violence and in the interest of keeping the marketplace of diverse people and diverse ideas (their words) safe, the best way to do that was simply not act as a venue for the discussions. "Maintaining civil and respectful dialogue within the big tent is more important than any particular session," the statement reads.
