Internet and Anonymity

I believe that every human has an evil side in his/her mind.   And one shows that when nobody is watching him/her.  It is same on the Internet like Seth Godin said in his article.  Fraud in ebay and Vandalism is Wikipedia are the examples of that.  When you just see these kinds of activities, it seems that we have to make the Internet without anonymity in order to make it clean.  

But still, online auction is still going on between anonymous sellers and buyers like Rheingold said in Smartmobs.  And many users have trusted on line and did good job in the anonymous world.

Also,  I understand that Internet's anonymity has made web activities more active and different from reality.   I've seen many people show their different personalities in the web or their blog.  Especially, for those of people who are introverted and very shy the Internet has done a good job introducing the whole new world and attracting them to participate and show more of their reactions.  Well, this is not applied to every shy person, but it is better for them to face computer screen than to face the person.

What could be the better idea? well, with all the same information about us, it will the duplicated world of reality. But then, we are still gonna have the same problems related to anonymity.  

My opinion is that we can make higher access for something important websites. Or we can make people to use the very accurate, real information to join the community or websites. But after that, make them use anonymous name in there, so that everybody can't see who one are, but when one did a bad thing, like a cyber police can find out to accuse one.   Well, it may raise more security problems as well.  It is so complicated and it is too late to return to the back.
