Bigadda And The Captcha For Bots
A captcha is a security measure to test if the user is human. It is widely used, and is reasonably effective.
Not if it is done the Reliance backed BigAdda way though. Bigadda requires a 5 character captcha to be solved before users are allowed in. The trouble is that the URL of the captcha http://bigadda.com/system/wordverification/verify.php?T=12345 gives away a little too much. In case you’re still wondering, it’s the captcha code (12345).
