However we as a company do not use CAPTCHA on our own websites. We are B2B and therefore want to put people off as little as possible when it comes to data collection, (volumes in B2B aren't as high) so we prefer to sift through the SPAM in the interest of maximising genuine enquiries. Obviously this is only manageable up to a point.My heart breaks for big B2C operators, as they are inevitably putting off genuine enquiries with onerous CAPTCHA images due to the issues of SPAM.Has anybody else found that CAPTCHA has reduced enquiries as well as SPAM?

My heart breaks for big B2C operators, as they are inevitably putting off genuine enquiries with onerous CAPTCHA images due to the issues of SPAM.

Has anybody else found that CAPTCHA has reduced enquiries as well as SPAM?

On the other post (the smart phone cam one) it keeps asking me "what is the sum of 2 + 3?" and won't accept anything (5, 05, 0x5...) Lets see if it works here.

There are too many instances of the security code being included in graphical images that are very difficult to read even with perfect eyesight let alone any form of disability. A text based question will do the job just as well, it is accessible and appealing to your real human audience.
