This is about the simplest anti-comment-spam measure you can imagine, but it’s probably effective enough for all but the most popular blogs. Here’s how it works. You pick a question and put a field on your comment for for the answer to the question. If the user answers it correctly, his comment is accepted. Otherwise it’s rejected. Here’s how it works:
Requires the comments plugin.
This plugin comes with Pyblosxom. To install, do the following:
Here’s an example of what to put in config.py:
py['mw_question'] = "What is the first word in this sentence?" py['mw_answer'] = "what"
Note that mw_answer must be lowercase and without leading or trailing whitespace, even if you expect the user to enter capital letters. Their input will be lowercased and stripped before it is compared to mw_answer.
Here’s what you put in your comment-form file:
The Magic Word:<br /> <i>$(mw_question)</i><br /> <input maxlenth="32" name="magicword" size="50" type="text" /><br />
It’s important that the name of the input field is exactly “magicword”.
In order for this to be secure(ish) you need to protect your config.py file. This is a good idea anyway!
If your config.py file is in your web directory, protect it from being seen by creating or modifying a .htaccess file in the directory where config.py lives with the following contents:
<Files config.py> Order allow,deny deny from all </Files>
This will prevent people from being able to view config.py by browsing to it.
