Hi

I've had a look at that myself (Of course, I deleted those files from my HD immediately) and had found that some of the JPGs don't actually contain childporn but a text that asks the users to stop distributing childporn.
As I think this is a good idea, I made a picture with the GIMP showing the following text:

"Please be aware that the possession of child porn is a crime and that you can be put into jail for it!
I know from a trustworthy source that the police are actually participating in the network and are doing IP-backtracking.
So, if you distribute/download such material over the net, you're in real danger!
For your own security: If you own such material, delete it!"

I then saved the file under a name that would assure the right persons to find it "worth downloading".

What do you think about this strategy?
