The same technique could be used to scrape a registration form for "What is" style questions too.

This is something like simultaneous action. And after correct input he gets more, and more and... finally he gets babe striped off completely. I hope you got basics. ;) PS Its all about human factor It goes something like this:

Do you know how they did it? A little knowledge about how they did it might help us have a better dialog about how to stop it. BTW: I still stand by my human test. @Shazalakadze:
