Coolnepali, There is a law in this country which does not allow the minors ( people under 16) to surf internet without the supervison of an adult. At home parents are responsible, at school teachers, and at internet cafes minors are not allowed at all. If we are following the law, children will never come across such things. If they come across such things, it means someone is breaking the law, parents, teachers or the internet cafe staff. The better thing to do is to try to follow that law rather than scrubbing everything out of sajha or any other website due to fear of children seeing them. This law should be enforced everywhere in the world.
