I was thinking about a way to use a similar idea but to dramatically
increase the ability to thawrt bots.

The idea is to use the idea that humans can use context and patterns to
understand much better than computers in such cases as the following,

So the idea is to ask the user a very simple questions that is written using
misspelled words and such so that it makes it almost impossible for
computers to recognize what the answer is. The question can be graphically
manipulated so that its also visually harder to figure out like a normal
captcha.

Besides changing the order of the letters in a word one can deliberately
change letters so that the word doesn't make sense but in the context is not
difficult for a human. One can even use bad grammar and a few other things
to make it more difficult.

I was thinking that one could create a very large database of such things in
different languages that sites could use.

What do you guys think?
