W3C Working Draft

In response to this 'Inaccessibility of Visually-Oriented Anti-Robot Tests Problems and Alternatives' paper.

I will comment this paper folowing the table of content

About : the problem : a false sense of security

Right, the value of a simple visual verification is low, but the value of a global anti robot system is very high.

About : A hierarchy of needs

About : privilege

I don't think this one adds value to the paper : implementing security or preserving privilege for certain user are synonym.
Security without privilege is useless, preserving privilege implies implementing security.
I'll forgot this one.

About : identity and humanity

My opinion on those two notion is that they are orthogonal.
