spamquestion is a simple PyBlosxom plugin that helps to prevent
A randomly selected question is shown on the comment form for a
blog entry. The user must answer the question correctly in order
to submit a comment. The approach works because each blog will use
it's own set of unique questions that are easy for a human to deal
with but are virtually impossible for a computer to answer unaided.
This makes automated spambots ineffective.
Unlike CAPTCHA based anti-spam systems, this approach does not
disadvantage visually impaired users and works even in text only
The question is written to the "spam_question" template variable.
The user's answer is expected in a "spam_answer" form variable.
These two items need to be integrated into the comment form template.
Requires: The "comments" plugin and the "session" plugin.
