When I started using the web back in the 90's, everyone used to use a handle/nickname and so it was never easy to link an online person to a reallife individual.
These days everyone is encouraged to enter their real name, DOB and telephone number (see Facebook, Twitter, YouTube) which then creates a link to a real person.
I think the web was better because it was anonymous, rather than anything else really. If you had "SuperHardLord" posting abuse at you on IRC, it didn't really matter. However if you have a Twitter user with full photo and details doing the same, it feels much more personal.
