I've got a forum-like area on my site, where people can ask questions and sign-up as a member etc. It always used to have a CAPTCHA on it to stop spam sign-ups, and for guests to post, but I recently installed a behind-the-scenes spam prevention script instead and removed it. To my surprise, the number of people signing up, and guests asking questions, shot up. By quite a lot.
It seems that the CAPTCHA was either putting a load of people off, or preventing genuine people from progressing further. And it wasn't a hard one either -- i thought it was actually quite easy (which is one of the reasons i removed it). Any person with more than two brain cells could have filled it in.
So I was just wondering if CAPTCHAs are more trouble than they are worth, given that there are so many other ways to stop spam nowadays.
