To be fair? Yes, let's be fair and let the article spout... whatever, I didn't pay for it.
A child playing a game is still experiencing the real world. There are important distinctions between games and reality, but this has to do with the platform. I don't know how far these vigilantes "go after" their suspects or how they verify their information points to the correct individual, so I cannot defend them; but to say that real people interacting through a game is somehow lesser than being in person diminishes the problem. It's the same problem Yahoo chat rooms dealt with in 2005. For the platform, or the FBI, or any other government agency to focus on the vigilantes instead of the paedophiles speaks volumes on its own.
I'd agree "evil" might be hyperbolic, but it's not like Legos are made out of bamboo or aluminum, either.
