seemingly outstanding immediate success in spam registration prevention turned out to be a dud.
In the days following the upgrade something was broken in the CAPTCHA method and the verification image was no longer being displayed. the spam bots could not get in - which was good. our fellow riders could not get in either - which was bad.
