The internet is more and more convenient but more and more dangerous. You can approach to anything via the internet, but on the other hand the bad things like violence, bully, pornography, etc are easier to approach as well. Because children are too young to distinguish between right and wrong, they might be influenced by these bad information, or even be inflicted by those things. The worst part is that they may learn the bad thing via those bad content and lead them to crime or even worse in the future.
