Since VRchat lets users create arbitrary avatars its only a matter of time before somebody creates a flickering avatar (like the Pokemon cartoon episode that caused hundreds of seizures when broadcast in Japan) specifically designed to cause seizures. With VRChat one could get very close to people essentially filling their VR headset's display with their avatar, focused directly into the victim's eyes by the VR's optics. Kind of scary-- the promise and the peril of user-created content. Some trolls notoriously did this by embedding Flash into an online forum for epileptics.<p>I wonder if it might be revealed if/when VR gets a wider adoption that VR's unique photic environment might cause the triggering unique types of epilepsy.
