The plugin is currently version 0.9 Beta. == Description == [BotProof](http://www.botproof.com "BotProof") Captcha is a free anti-spam and anti-bot solution which uses a new and unique type of [CAPTCHA](http://en.wikipedia.org/wiki/Captcha "CAPTCHA - Wikipedia"). We offer a service that will change the way you think about protection from spam and bots. This is the next generation in captcha technology, Captcha 2.0. No more distorted letters that annoy your users, and no more [OCR](http://en.wikipedia.org/wiki/Optical_character_recognition "Optical Character Recognition - Wikipedia") bots breaking through weak captcha implementations. BotProof captchas use dynamic information to display hidden symbols in unique ways that are harder for bots to break through, yet easier for your users to read. Our technologies are state-of-the art, with many customizable options. Because we deliver our captchas over the Internet in real-time, we can offer a variety of implementations. We can react quickly and enhance the technologies, to always stay one step ahead of the bots. Our software can also be used to protect your personal information and your identity.

Most themes do. == ChangeLog == = Version 0.9 = * First Beta release of BotProof Captcha WordPress Plugin == Frequently Asked Questions == = Why do you use random letters and numerals, instead of words from the English language? = The captchas you see online who use words from the dictionary are doing so because their noise makes it too DIFFICULT for a human to read. (Noise is the distortion or lines they add to a particular symbol.) But using English words is less secure. Once a bot can guess a few letters, it can search for words in the dictionary to solve the other unreadable letters. Because BotProof Captcha does not need to distort the letters and can make them more readable, we can offer the added security of using random symbols. Our captcha also therefore does not depend on the user speaking a particular language. = Are captchas secure? I heard spammers are using other sites to solve them: the captchas are sent to a different site, and the other site's users are asked to solve the captcha before being able to enter or access a valuable resource. = Captchas offer great protection against abuse from automated programs. While it might be the case that some spammers have started using redirection sites to attack captchas (although there is no recorded evidence of this), the amount of damage this can inflict is small (so small that we haven't even seen this happen). Whereas it is easy to write a bot that attacks an unprotected site millions of times a day, redirecting captchas to be solved by humans would only allow spammers to abuse systems a few thousand times per day. The economics of this attack just don't make sense. Every time a redirection site shows a captcha before giving access to a resource, they risk losing a customer to another site that doesn't do this. We welcome references to any articles, evidence, or research in this area. == Screenshots == 1. BotProof Captcha Settings 2. BotProof Captcha in a WordPress blog
