I recently had customers telling me that the code it gives is to hard to read. I'm not a programer, but can get my way around. Can anyone help and tell me how to simplify and make the code in reCaptcha easer to read for customers?

Thanks

Unfortunately, spambots already are pretty good at reading any CAPTCHA (including reCAPTCHA), and making it any easier for humans just makes it that much easier for spammers. Any sort of "what text is this" that is readable by most people is already readable by most bots. The situation is worse if there is audio to spell out the letters or pronounce the words. Much effort is going into stopping bots (automated visitors) in forums and other places where members or visitors can enter text (e.g., feedback and product review), but not much progress has been made.

 

Some rely on visual puzzles that are unusable by the visually handicapped (and may therefore even be illegal in some jurisdictions). Others require specific I/O devices such as a keyboard or a mouse, and might not work on, say, a tablet. On forums, the most effective means of stopping spambot signups seems to be making the applicant answer one or more questions in the subject area that the forum covers. As this is free-form input, it can be very difficult to devise code to accept all valid answers while rejecting all invalid ones. Note that math puzzles (e.g., "2 + 3 =?") are extremely easy for bots to answer.

 

I don't know how you are using reCAPTCHA with osC, but be aware that "turning down" the difficulty (assuming it can be done) will likely result in your being flooded with spam.

Thank you for taking the time to get back to me. I understand why, just sometimes it is hard for me to read what to type in. But it has stopped alot of bots that my IP trap does not catch. I needed to ask for the sake of pleasing my customers. Thanks again.

Google announced last fall that they were going to change the images to numbers for the very reason you state. They seem to indicate it should work as long as you are a person and I have seen it but not every time. So maybe it will get better over time. A few shops had me add a message beside that box telling the customer to click on the recycle button if they couldn't read it. Clicking on that image is not an obvious thing for some people so you may want to try adding something like that to your shop until google switches over completely, assuming they will.

You could do without it. Action Recorder and a simple "maths" question (what is n + n) would beat 99.9% of spam bots.
