It seems like the author is emotionally invested in this topic:
> Given my circumstances, I have seen first-hand, the psychological damage a pedophile’s actions cause. The damage done to these children is permanent and no matter how much counseling and assistance they seek – the experience is forever embedded into their self, shaping (and sometimes limiting) what they become as adults.
I can't pretend like I really get this because I've never dealt with pedophiles or pedophilia first-hand but I can agree, however, that people that hurt children are doing something morally wrong. With that said, this kinds of vigilante-esque behavior can be (and often times is) the absolute antithesis of justice.
> On two different occasions I contacted the FBI about the project and offered to provide full sets of data that I had collected.
Since OP tried to approach the FBI on two different occasions, it doesn't really seem to me like this was merely an innocuous "security" experiment (like this one: http://www.tomsguide.com/us/spoiled-onions-tor-network,news-...). It seems like OP really feels a deep hatred towards pedophiles and was, in a sense, out to get them.
Thankfully, we have the justice system that handles this for us. These are people that try to be impartial, fair, and just. When accused, we have the court system -- a system that values innocence until proven guilt. I hope I won't be taken out of context here. I'm not defending pedophilia (or drug trafficking or murder -- a few other Tor commodities). Do you really feel compelled to "get the bad guys?" Great. Go to a police academy or go to law school. Real life isn't like a superhero graphic novel. The law, for the most part, works. More importantly, it provides some boundaries for those that enforce it.
I had to read Mill's On Liberty in a Philosophy of Law class I took a few years ago and Chapter IV, Of the Limits to the Authority of Society over the Individual, really stuck with me. I would strongly suggest OP give it a good read: http://www.bartleby.com/130/4.html.
