Captcha on knowledgebase/troubleshooter comments

[richyc]

Hi,

Is anybody else seeing a growing amount of "spam comments" to the knowledgebase and troubleshooters (not tickets)?

If so, is there a way of enable the captchas to just those sections or add a "Allow comments by registered users only"?

I would very much like to see a captcha-feature for comments. I have manually disalbed comments since I get several hundred spam comments each week. Here is what I've added to the top of index.php:

PHP Code:

if ($_POST['_a'] == 'addcomment')
{ 
    exit("Comments are currently disabled!");
}

I see hundreds of spam comments every week.
We have not disabled this function because we have to authorise any comment before it gets in to the KB but we have to manually delete the spam which is a real pain.

I would appreciate any help in setting up a captcha-feature to help us
