Is it harassment? And who are the propagators of said harassment?
So far, I haven’t seen a real case of harassment from those who stand on virtual rooftops and shout how they are being targeted — I’m sure that those cases exist, but not as the phenomenon people describe.
When someone invokes the accusation of harassment, first we need to check how he or she communicate online and whether or not the interaction they describe is actual harassment or an adequate response to something they are the instigator of.
People like to bring up GamerGate as an example of “targeted harassment.” All the “victims” who stand on podiums and cry about their aching feelings are found to be the instigators and on occasion even creating or calling for the harassment of others.
As for Twitter: It’s a platform for gotchas, shitposting, and memes. There is the occasional link or relevant image with substance, but for the most part, people arrive there to be idiots.
Now, as it pertains to VR and gaming in general, “if you can’t stand the heat, stay out of the kitchen.” The same way you won’t require a car manufacturer or the driver to limit the speed of a car to 10Mph because people may be hurt, you can’t ask VR manufacturrers and users not to use the device for the purpose it was designed for.
