The thing I've always read about these is that they tend to discriminate |
| 6 |
against those for whom the language isn't their native language. |

Math problems are generally agreed to be reasonably universal, however, |
| 9 |
tho that can change if wording is chosen to try to defeat a machine |
| 10 |
solution (running into the language problem again). Spelling captchas... |
| 11 |
tend to run into problems with folks that can't spell. That's apparently |
| 12 |
a big enough problem a lot of sites try and reject spelling captchas. |
| 13 |
|

Perhaps a mix such that users can try again with a different category, |
| 15 |
however... |
