|Example # 10: Human
vs. robot verification
Date: 26 january 2005
When registering a new site to this swiss search engine, and
to avoid robots submissions, a form asks you to enter a series
of 8 characters into an input box. Unfortunately, the last one
is cut, and there is no way to know if this is a "C",
"G", "Q", "O" or "0"
(a zero). See it for yourself !
A nice way to exclude both robots and humans in the process
! Who will submit a site then ? No wonder that only 6132 sites
where submitted at that day... (provided you can find the submit
link, which is another challenge).
Important note: the error is not appearing in all instances.
Sometimes the 8 digits appear, sometimes not. You might need
to refresh the page for being "lucky", ie to see it
as shown below. I was a first timer...
Errors / Recommendations:
Obviously to correct the problem so that the eight characters
always fit into the coloured box.
Eventually also, correct the typo and remove the comment "case
sensitive" comment, since all letters are in capital...
