The widespread use of CAPTCHA in low-volume, low-resource sites, on the other hand, is unnecessarily damaging to the experience of users with disabilities. An explicitly inaccessible access control mechanism should not be promoted as a solution, especially when other systems exist that are not only more accessible, but may be more effective, as well. It is strongly recommended that smaller sites adopt spam filtering and/or heuristic checks in place of CAPTCHA.
Well, it was at least fun testing the CAPTCHA solution. I'm going to put it away in the attic for now. ;)
