I’ve been looking at reddit.com and they don’t require new users to enter an email address. Instead, they only require users to enter a captcha.
I’ve been considering only using recaptcha to verify new users, instead of both an email address and captcha like many sites do.
What is the use of verifying both an email address and a captcha? It seems more likely that a bot could spoof an email verification instead of a captcha.
I’ve lost my Reddit password — and there’s no way to restore it.
The point of having a validated email is not only seeing that someone can receive an email and click a link in it; a robot can do this, too. The email is a route back to the user: it serves to restore lost passwords (and people do forget passwords), to notify of important events, etc.
OpenID is also a great registration / login option, minimum hassle for the user, and you get a validated email with it, too.
