Are these the kinds of trolls that hunt people down in the physical world, or send nasty letters to employers to get people fired, or send SWAT teams to people's houses?
All of those have happened. All of those are trolling.
The media both reflects and creates usage. Therefore, yes, it is very much right in this case.
Whining that it's un-PC isn't going to help you.
The exception to that is technical terms used in a technical context. That doesn't apply here.

I would be interested where you fall on zero tolerance.
Put another way, if a person is being irritating (in text, at that), and you find yourself feeling terrorized, there's a massive failure of communication occurring.
Yeah, I don't think it is.
