By children, around what age range are we talking about? 8 - 10 years old? 12? Either way, I think it's horrible that this kind of practice is being tolerated in some countries - good working conditions or not. Children are not meant to be used for labor. It's never going to be okay whether it involves manual labor or simply an online task. This is parallel to slavery - almost even worst. Countries where this is being practiced should strictly enforce laws against child labor whether its tier 3 or third world or whatnot.
