This plugin allows you to add CAPTCHAs to your site in the form of simple questions requiring simple text answers.
For example the site would ask "What animal is Bugs Bunny?" and the user would need to type in "rabbit" or "a rabbit".
You can select where the plugin should be used:
- anonymous item forms
- anonymous comment forms
- new registration forms
- anonymous messaging forms
You can configure your questions and a list of possible answers for each question in the Questions field of the plugin settings. Each line of the questions field should have the following format:
Question text? Answer1|Answer2|...|AnswerN
The string from the beginning of the line to the last question mark (?
) is considered to be the question text. Note that the question text may contain multiple ?
s.
The string after the last ?
until the end of the line is the answer to the question. It is possible to have multiple answers for the question, and in this case, each answer should be separated by a pipe |
. Answers are case-insensitive.
Try to come up with questions that are specific to your website. The questions should be constructed in such a way that your visitors will be able to answer them easily but not be too predictable for a spam bot writer.
Do not forget to include all possible forms of the answer, for example:
How much is 5 plus 4? 9|Nine
The above should accept answers such as "9", "nine", "Nine", "NINE", and all other possible upper, lower case combinations of the word "nine" as correct answers.
The plugin will not be effective if you do not configure it and supply your own questions. Using default questions (for older versions) give spambots the opportunity to answer automatically because they already know the questions and the answers.

This really should allow per-blog questions. In a multiblog system, the questions that readers of one blog could answer might be different from those of a reader of a different blog. Of course, it should merge the site-wide and per-blog settings, for those whose multiple blogs don’t need seperate questions.
