Exactly. Also 'entrapment' (seducing people into committing a crime) is illegal in Holland. So the pedophiles found in the Netherlands in this way will likely not be prosecuted. However, I get the feeling that this was not the intention of the project. I think they just wanted to show how widespread this issue is, and get attention for it. So that 'legal' (whatever that is in your country) measures can be taken to stop this.
