That's the proof that its working. As you say, when the child molesters are really and truly safe to speak their minds, everyone is.
These people would exist anyway. Sometimes humanity sucks. Interesting though, TOR allowed you to study them in a way you would never have been able to otherwise. It merely disgusted you, but it could be a valuable resource to someone who studies how people break and thinks about what might be possibly done to help or hinder them.
Whether or not they exist anyway, it seems obvious to me that a supportive peer group is going to increase their effectiveness at predation.
Perhaps they talk about it so much that they don't get around to doing it--studies on violent pornography and child pornography sometimes find that viewers use them as a safe outlet to actually doing it themselves. But that's a huge gamble. At present, TOR is simply enabling child predators to be better child predators.
Imagine a perfect world. Not a world in which everybody is perfect, that would be boring, but a world in which institutions really function. In such a world you'd expect to find this kind of forums, find them anonymously and relatively easy. They'd be up and running for years. And they'd be fully staffed by people well-versed in finding and helping pedophiles (cops, psychiatrists etc).
You can't check people at birth and see if they have criminal tendencies. It's unethical (and impractical) to watch everybody all the time. What you can do is make sure there are places where they'll gravitate naturally towards, and control them for your benefit.
The right way to dismantle a pedophile network is to arrest everybody, steal their online identities and keep on posting the materials they already have. Otherwise you're just playing whack-a-mole.
Although, logically, it doesn't allow for infiltrators (e.g., police) to enter the forums and attempt to build enough cred to initiate convincing these predators into doing something stupid, for instance dangling financial rewards in front of them for real world meetup for exchange of goods, etc.
This is how law enforcement has been working on carding forums. And while I don't think the enforcement is effective for that, since the financial incentive is always there, I do think there is a finite supply of people willing to prey on children for money and that there's a possibility of capturing the vast majority of them.
The problem aren't the people who do it for money :/
Why would they ever meet up? What goods are there to exchange, other than, uhh, tips and tricks? I wish I could share your optimism, but I decidedly don't.
Sure you can catch some by that, but what then? The remainder will be resistant, and very used to how to phrase things, and also noticing attempts to play them into giving something away. We're also talking about people who exchange tips on how to get at actual children, remember, and you can do that fine without giving anything away. It's like open source, no strings attached, works fine with dead mailboxes.
Unless an actual law enforcement person involved with this confirms it's usually that easy, I file all of this under rationalizations... understandable ones, but still. Because yeah, this stuff can mess you up, and we always seek to return to normality.
It's very easy to say all this until you visited those places. I wouldn't want to, I remember trying to talk with pedophiles in a public, above-board forum, (where they were of course always beating around the bush, it was all about "simply loving children", who have a right to be loved blah blah), and I couldn't even take that for more than one post, I read the replies and thought fuck this, fuck you people, I don't need this in my brain. But that was harmless - the dark, uninhibited underbelly of that? WHOA. I wouldn't have the nerve to read an hour of that - just talking about text here, that's enough for me kthxbye :/ - but I take it seriously, because I think I can kinda imagine how it might be. I know just ranting about it also pointless, but I also disagree with hand-waving it away.
If you read "Kingpin", even though the owner of one of the top carding forums could have just traded digital goods and been fine, he choose to dabble in physical goods for the money/whatever. That was how he was caught. I'd surmise the predators are not too different, though perhaps decidedly more cautious.
It's where people (think mostly the lowest common denominator of wannabe hackers like script kiddies and such, i.e. not just bad but fairly inept) go to learn how to and share information about stealing credit card information, usually leading to minor levels of success if they keep at it, it seems.
I bet law enforcement agencies crawl those places frequently trying to lure child molesters. And that's the good part of the story, without the Internet in general or specifically Tor there would be little chance to catch those pricks. The more they express themselves the easier I guess it gets to nail one or two of them eventually.
