Last week, Adrian Chen at Gawker published a long profile of infamous Reddit moderator Violentacrez, described as "the biggest troll on the web." In addition to exposing Violentacrez' real-life identity, Chen's profile reveals the seedy underbelly of Reddit, a massive social news aggregator that touts itself as the "front page of the internet." Given Reddit's astounding traffic stats -- the site attracted 42 million unique visitors just last month-- this assertion isn't that far off. Reddit has become a cultural juggernaut; it would stand to reason, then, that one of the biggest sites on the web would harbor one of the biggest trolls on the web. The question is, what exactly does that label mean? If recent media coverage is any indication, the term "trolling" includes everything from harmless, and perhaps even helpful, mischief to defamation to watching leaked crime scene videos to outright harassment (sometimes described as "cyberbullying"), either of someone known to the troll or high-profile public figures.
