Then what you are saying is that if a thief write a booklet on how to install a lock he can't pick and leaves it at the library for me to find and then I fail to read the book and fail to put the lock on my house, it is my fault he robbed my house and he can't be prosecuted?
Yep, I am saying it is not enough. Those measures take knowledge. Google (and other SEs) make more than enough money to set up a system that idiot proofs it. Any other industry in the world that handles potentially dangerous material is required to do so.
I have often marveled at the fact that while they have measures that tell them where to stay out of, they still have not taken steps to allow you to tell them where they are allowed in. It might throw a kink in their business model, eh? Why should SEs be inherantly allowed in? It seems to me that it would be better for everyone if you had to make an effort to let them in rather than to keep them out.
It would force people to learn the system or at least reduce the damage done by people who don't learn it.
