Should people be allowed to obscure their identities online?
Matthew Murchie, 18, Imperial College London
The internet's widespread influence and easy accessibility has opened doors to new methods of crime.
These include fraud, cyber-bullying and identity theft.
As a solution to this problem, some people suggest that internet users should not be allowed to remain anonymous. This, however, would limit the usefulness of the web.
The internet is the most powerful tool we have for free expression. Yet many people only feel comfortable publishing their opinions online if they can do so anonymously.
This is particularly true of citizens in oppressive states where airing critical views can land you in trouble. Preventing people there from hiding their true identities online would effectively cut them off from the outside world.
