I think it's an important question to ask. Many people critique the term cyber-violence as well and ask if it is something new or just more of the same. Certainly we know that off-line and online are blurred. I think you're aware of all these things.
We try to look at the technology and ask what specifically is new or different about it. Some people like to focus on the anonymous angle—you can be anonymous—but many of these platforms are encouraging people to be “authentic”, as they call it, and to use their real names, etc. There's a lot of push-back on that as well.
I don't know how different it is in the off-line and the online environments. That's where I'd leave that.
