How would you change/adapt the internet?

The internet can be such a powerful tool but can be strongly abused. There are so many things on the internet and people tend to abuse the power that is given to them via the internet. I think there should be restrictions of what people can do on the internet such as posting things. I think that more monitoring on the internet should emphasized especially for students in school. So many times we here about people searching different things on the internet that is illegal and harms people but people get away with it such as how to do different things. I think more emphasize should be placed on monitoring internet usage. I know this would be an extremely difficult task but I think we can do a better job than what is happening now.
