By default, I rather hate the idea of CAPTCHAs. They tend to be horribly inaccessible and ugly. They cause usability issues of all sorts and while blocking spam they also have a tendency to block legitimate messages as well.

Except this one. I’ve come across a new open API called TextCPATCHA which has none of the accessibility issues of reCAPTCHA (and similar) while all the benefits. I even ran this by a friend of mine who’s an accessibility consultant and he gave it his stamp of approval, saying the only issue was the one they mention on the site: People with cognitive disabilities will have trouble with them since they’re logic based.

Now I’m looking at what it would take to implement these on Symphony. My guess is I have to modify the Save Message and Save Comment events, correct? Any tips before I dive in?
