If the member validation was perfect bullant then you would not be back here again under a new sig posting links to the same content as in your last incarnation
huh? whatchya talkin' about boy????
If your talking about this link
then go look at devshed, web developer, sitepoint and the many other websites that link appears on. If you think they are all posted by a single person then you've got rocks in your head
I can't remember which site I copied that link from originally. It was a few years ago now.
As I said in an earlier post, the captcha on the registration page is laughable as it's very easy to break by anyone who knows what they are doing. Instead of critisizing the link why don't you read through it and learn from it how to build at least a half decent captcha and get rid of that joke of a captcha currently being used.
If you've got people registering that you don't want then you've only got yourself to blame because it's very easy to bypass the alleged "defence" against unwanted registrations you are currently using. If you keep knocking people trying to help you and advise you on your weaknesses your not giving them any disincentive to show other people how to easily bypass your current "defences" against unwanted registrations.
