I think bots have an easier time reading captcha than humans. I was locked out of my phpbb forum because it took me forever to get the captcha correct. Also, have you ever listened to the audio for reCAPTCHA? It's practically nothing but noise. reCAPTCHA's tagline is "Telling humans and computers apart." Yeah, only the bot will get it right. :P

Question / Answer
This technique was introduced during the phpBB2 days and is much easier to
manage with phpBB3 since a board owner can set up custom registration fields.
The basic premise is this: the board owner sets up a question on the
registration page that requires an answer. The answer could be provided in the
form of a drop-down list or other input control, or alternatively it could be an
open text field that requires the user to enter the answer manually. The
question can be related to the primary subject matter for the board or it could
be a general knowledge question like what is 2 + 2 or what color is the sky. In
any case, the question is supposed to be easily answered by a human and
impossible to answer for a bot.

Most boards that I manage, the spammers crack any new QA we come up in a matter of days. They've got cheap slave labour that costs nothing, so getting a human to find the answers to the questions is still dirt cheap. And you can only come up with so many questions and answers before falling into easily crackable patterns. So QA is pretty useless and Recaptcha's been broken a long time ago (we still got way less spammers signing up with QA than Recaptcha).Former endorsement revoked.

The default CAPTCHA image that comes with VB is really hard to read. But reCAPTCHA has been pretty awesome I thought, no problems so far reading it and if you get a hard one to read you can simply refresh it.leftunderground.com - Progressive Message Board Open To EveryoneComment

I can't read the CAPTCHA at most websites. I can't make out most of it, even the one that vBulletin uses. Then I end up trying so many times I get locked out of the website.
I thought I was the only one that had trouble reading that junk.Comment

They are extremely difficult to read, especially RECAPTCHA which doesn't always even use real, or even pronounceable, words!
I dropped the whole caboodle a long time ago and switched to question/answer. Had no real spammer problems since then and the questions are ones that any English speaker would know. Non-English speakers shouldn't be signing up to my site anyway since the only language we use is English.MARK.B

Around the end of 2010 reCapcta was broken by hackers in a systematc way, and there seems to have been lots of exploit code around. Search the web for "recaptcha broken". I stopped using recaptcha then and spamming went from hundreds per day to zero. If the recaptcha texts are getting harder to read now, it may be a countermeasure from Google (who own/run reCaptcha). However, there are alternatives. Q and A seems to work better for most, at least for smaller sites, where less worth the effort for spmmers to sign up manually.Comment

Captcha is almost impossible to read and extremely frustrating. The worse part it doesn't work. Here are the steps I use to prevent spammers.
