reCAPTCHA

[NogDog]

If you are looking to implement an anti-spam "CAPTCHA" on a form, you might want to look into reCAPTCHA. It serves a secondary purpose of helping to digitize optically scanned books.

I integrated it into the "Email Me" page on my personal site, and it was pretty painless. They have a ready-to-use PHP class which was quite simple to use.

that's funny, i looked at the exact same site today out of the blue also looking for a captcha service. Although I havent checked them out yet I certainly will

I'm currently working on the various steps required to try to lessen the bots' impact without user/visitor input. The captcha's are getting more and more confusing to the visitor as they try to outwit the bots. I know there is no fool proof method of stopping it, but captcha falls into that pit as well. Instead of making the visitor jump through hoops, I want to try to do all the work on the script's end. It remains to be seen how successful that will be 🙂

thanks,
