Messy situation
Ok...so what we have here is a guy who went out of his way to expose pedophiles (a good thing) who used the same skills to ruin the life of a colleague (a bad thing) who, rather than suing the crap out of the guy who ruined his life, launched a DDoS against Rolling Stone and other companies (a dumb thing).
Seems to me that the biggest losers in this mess are the victims of the pedophiles these men could have been exposing if they weren't so intent on going after each other and news outlets.
