CAPTCHA Anti-Spam System Made Stronger and More User Friendly The
CAPTCHA system used to help prevent unwanted form submissions (spam)
has been upgraded. The new format is more complex, making it harder for
an automated system (spam bot) to decipher. In order to provide a
frustration free user experience in light of this stronger format,
validation codes now consist of numbers only and can be regenerated by
the user should they have any trouble with legibility.
