Integrate CAPTCHA into MT Comments
In the ongoing struggle to prevent comment spam, I would like to include a measure that would certainly eliminate all bots from posting to MovableType. I would like to implement a CAPTCHA into the mt-comments.cgi or comments.pm so that all commenters would have to validate against a graphic.
There are a couple of sites that have something similar already functioning, for example, MrBlog has this working for his Greymatter. I know that there are existing Perl & PHP modules out there, I just don’t know how to integrate them.
As I mentioned before, I (personally) don’t give a hooey about the accessibility issues involved with using a CAPTCHA. Maybe that makes me a bad person. I’m OK with that. (Actually, Paypal has a quick ass work-around that involves the user actually listening to the random series.)But I’m not OK with the spam I’m getting in my comments.
It looks like we’re just one or two smart coders away from making this happen. Help!
