Alternative to CAPTCHA ?

Hey there,

I would like to know what could be efficient alternatives to CAPTCHA systems ? Do you believe email confirmation is a good anti-spam method (I find it a little annoying on the user-side) ?

Re: Alternative to CAPTCHA ?

When we use captcha , it becomes sometimes very annoyin when we are unable to read and in case of email confirmation method , some times the mail gets delayed to reach us and we miss the membership . There should be a better method to keep away spammers

Re: Alternative to CAPTCHA ?

I've been trying to look at alternative methods (eg image captchas) but it all look rather complicated, I have to say ... Maybe I'll go with a very simple catcha to stop "elementary" bots, and then I'll try other ways to filter spam (IP filters, etc ...).

I guess there must be a lot of research going on to improve Captcha algorithms ... ?

Now a days Spam filter like CAPTCHA is necessary part of website but it needs to be checked whether working properly or not. I have seen many websites where the CAPTCHA not functions that will be a loss for the webmaster. Even genuine visitors who wants to communicate or some other cannot do the same.

I don't think there is any alternative except Q&A. Email authentication is not legit anymore because spammers have some kind of script which will automatically do email verification things..So I guess, captha is best for preventing spammers.
