It's effective, but

disturbing.

I wouldn't say he was a nerd, but he had the nerdish twist in him.

So a lot of the stuff we actually were interested in as well.

So he was... easy to start talking and then i think over time we just transposed a bit of our personalities and shifted from what he was and the people on the other side they just sort of accepted as an evolution in the communication but yeah like when they sort of wanted to shift to child abuse those were the difficult conversation i would say

The strains of inhabiting this world are beginning to show, and Libor is finding that months of pretending to build relationships with abusers is starting to blur the boundaries.

I've realised after time the hardest part was...

And it might sound like from movies or something like a cliche, but just getting too deep.

By now, Libor has spent hundreds of hours watching Ski operate on the love zone, but it's still confronting to see the kingpin offline, face to face.

In a way, he looked like what I expected, like he had that sort of...

Paul and Libor

And as investigators infiltrate the love zone, boundaries get blurred.

you can't be just pretending for six months at some point you have to start really putting your real person in otherwise it's just not gonna go anywhere

Except the eyes of Libor Jok, the undercover Argos agent, now masquerading as a VIP on the board.

It was apparent that there was pretty rigid structure in there, but IO was right up there.

Like, he was behind a lot of the software modifications...

IO

in particular, quite high.

He didn't post, or he didn't post material, and he didn't post anything about the... interest everyone had, just posting about what he's doing to the board, how he's fixing these, upgrading these.

So he was pretty much just keeping people abreast of where the technical side is going and so on.

to get an idea of all the different personalities on the site, like a who's who in the zoo.

You would just log in and you would see, oh, there is maybe 50 guys logged in at the same time.

But it was just, you would just go through, read the new posts.

And as I said, my main thing was, oh, let's do the downloads.

But I also had a little Excel spreadsheet where I was like, yep, these are the guys who run the show.

This is what I know about them.

These are maybe guys I could be interested in and so on.

Liebel has started chatting to him in the forums and is getting a sense of how he operates online.

Lebor's been on the road all day without a toilet break, and nature's calling, so he finds a nearby bush.

And halfway through, this man in camo gear comes right in front of me.

I don't know if I hit him.

Maybe I did.

Maybe he was hiding there and he got a bit wet.

But that was Mr Smith.

He was actually hiding in the bushes for a couple of hours, waiting for us to go away.

videos fit in one terabyte? Around 500 hours worth of movies.
