Type less captcha on /b/

I know, back to /b/ and stuff.

I tried to type two times the same captcha, changing the recaptcha id with firebug and it worked. So, with js and a php site, is possible to type 10 captcha and post 20 posts without typing them?
And it's possible to make a service like that?

And someone can write worst english?

With an userscript you change the recaptcha id to a known one stored inside a localStorage database or something and fill it with the working captcha. The ``database'' entry would be like {id: 'theid', captcha: 'the captcha'}. The ``send'' button is modified to first try all the database ids, deleting them when they fail. If all of them fail, it will reload a new captcha and ask the user to solve it, store it in the database, and send the message.

The interface should also have a button to allow the user to write the captcha by hand, to extend the captcha database and reduce the possibility of a failure.
