Thet don't need to read English. They just
need to type the letters they
see on the image. Sure, you can have a small advantage if you know what
letters could make a valid English word (or if you have the captcha
dictionary installed), but a Brazilian which can read wikipedia should
have no problems typing the captcha.
If that is the case, why don't we change the CAPTCH for random letters?
You should probably ask Neil Harris, the author of the captcha generator
we use.
from his 06/02/2011 mail:
The wordlists themselves need not be secret: they are
only needed to
create easily-typed strings that are sufficiently large in number to
provide a moderate challenge to brute force guessing.
I have added a random captcha at
http://test.wikipedia.beta.wmflabs.org/
You can try adding urls at
http://test.wikipedia.beta.wmflabs.org/w/index.php?title=Main_Page&acti…
and
http://en.wikipedia.beta.wmflabs.org/wiki/Wikipedia:Sandbox for
comparing the presented captchas.
(yes, testwikibeta is quite broken right now, but the captchas show)
