I know I said laws vary from country to country, but I believe child porn is illegal in most countries, so if I was you, I would still report it, and just see what they say.

What's really sad is not only are these kids having pictures taking of them but also that they might be being abused in real life by people.

Something really needs to be done, so I'd report IP addresses even if you don't think that they're in the U.S. or whereever.
