Does anyone here know how to add captcha for comments on a wordpress blog to prevent spam? Also, what is the easiest way to clear out comments awaiting moderation? I ahve a lot of them building up and it is too hard to do manually. thanks
I wouldn't suggest you adding captcha to prevent spam. People are sick of filling out same forms all over again. Also, to run it properly addition library might be required. I think math comment plugin can be more productive. You can check out math comment spam protection If you persists with captcha, you can use cforms plugin
I agree, dont use captcha for comments, all people are encouraging commenters and you awant to decourage them Just use an antispam plugin, Akismnet is doing a great job for me
Try reCaptcha wordpress plugin, i was using it. It reduced my spam upto 60%, but it is irretiting for normal users to enter code everytime they comment so i removed it But the plugin is superb with nice tweaking options
There's the mycaptcha plugin You could check this out as well: http://wordpress.org/extend/plugins/wp-spamfree/
