E3 team, since you're doing work on the registration/login screen - this
might interest you :).
Note the big gotcha he describes, which very much applies to us...
"It is still possible for someone to write a bot to exploit a single site
by closely examining the DOM. This means that if you are Yahoo, Google or
Facebook, negative captchas will not be a complete solution. But if you
have a small application, negative captchas will likely be a very, very
good solution for you. There are no easy work-arounds to this quite yet.
Let me know if you have one."
In short, I think this would probably increase the effectiveness of our
efforts to combat bot registrations, but would likely not be a replacement
for our current CAPTCHAs. Chris Steipp would have more to say on this
front, I'm sure.
P.S. "E3" no longer exists ;-) See also:
