Joi Ito says this about Anonymity on the Internet
And I have to agree at this time, even though I have 99% spam in my inbox each day ...

Virus writers are always anonymous.

Vicious political lies (with faked photoshop photos of political leaders, or false innuendo about personal lives) are always anonymous as well.

Spam is anonymous.

eBay fraudsters are anonymous too.

It seems as though virtually all of the problems of the Net stem from this one flaw, and its one I?ve riffed on before. If we can eliminate anonymity online, we create a far more civil place.
