Websites that need a simple text CAPTCHA
About TextCaptcha
The TextCaptcha service provides access to textual CAPTCHA challenges via a simple JSON or XML API over HTTP.
The question is the textual challenge that should be presented to the user. The answers are the MD5 hashes of correct lower cased answers: you should be able to check responses from real users you challenge with the question against these checksums.
A text CAPTCHA is more accessible to visually impaired users than their image-based alternatives like ReCAPTCHA. Using text is also more flexible if for example you need to present the challenge over a text-only channel like SMS or IRC.
The problem with text CAPTCHAs is that they provide inherently more information than a distorted image. They are parseable, under the right conditions solveable. With the advent of contextual parsing tools such as Wolfram Alpha, such simple logic puzzles have become easier to solve programatically.

BotDetect CAPTCHA
BotDetect™ CAPTCHA generator is a non-stalking form-security solution that uses a mix of measures, that are easy for humans but hard for bots, to prevent automated form posting. BotDetect also provides an audio Captcha alternative to keep websites accessible to people with impaired vision, enabling you to make WCAG and Section 508 compliant websites. The years of Google’s relentless abuses of their organic and paid search monopolies, and the years of their equally relentless campaign of disinformation and FUD about captchas, took a toll among our former competitors there are only two viable players left. During its first decade, BotDetect was unique among Captcha generators in offering many different Captcha image and sound algos. While each of them was easily comprehensible to humans, the random use of multiple Captcha generation algos made the generated captchas extremely difficult to pass automatically.
