In the intervening years, the term “troll” has come to subsume all kinds of antagonistic online behaviors, regardless of whether the participants would describe themselves as trolls. I am wary of this new framing […] and whenever possible avoid using the term as a behavioral catch-all. Instead, I prefer to describe online antagonism in terms of the impact it has on its targets. So, if someone is engaging in violently misogynistic behavior, I call them a violent misogynist, as “troll” implies a level of playfulness that tends to minimize their antagonistic behaviors, or at least establish a firewall between the embodied person and their digitally mediated actions. (“I’m not really a racist, I just play one on the Internet” doesn’t account for the fact that, regardless of what might be in someone’s heart, his or her actions have a real and demonstrable impact on those forced to read yet another racist statement online.)
