Asks commenters to complete a simple CAPTCHA if they don't have a previously approved comment, or if Akismet thinks their comment is spam.
I wanted to keep comments open without having to review the spam folder--even though Akismet is very good, I don't like not having another set of eyes on it. Adding this plugin to serve a captcha only when Akismet flags a comment, and delete the comment if the captcha isn't completed correctly, has reduced my spam to literally zero. I'm incredibly grateful.
Downloaded recently, used the askimet settings and waited a couple of days only to see the amount of spam comments hasn't changed. Maybe I'm missing something..
Works as described!
What is missing:
* custom text when user fails
* custom text on I am human button
* a way to add newline character in those custom text (so that a nicer output is shown to the users)
* Automatic redirect to original page (ie back to the blog comments) upon failure
Best. Plugin. Ever. Well, I feel like that right now because after about a week of using this no spam comments at all. 1,507 spam comments blocked!
I've tried several other plugins that were supposed to accomplish this. By far this is the easiest, most effective and least obtrusive of them all. (And it doesn't break other parts of my site.)
Really, could not be happier with a plugin like this. Thank you!
1000+ spam comments per day and now zero. Great plugin!
Akismet does a great job of filtering spam comments; however, it still keeps the spam comments in the database. I was getting about 1,000 spam comments per day before I installed Conditional Captcha. I configured Conditional Captcha to immediately delete all comments that failed the captcha test, now I have zero spam comments making it into my database! Good job with this plugin.
I love it, because it sits invisible in the background until the moment one presses the submit button (comment). I use the Priimo Theme and it works great. Thank you very much!
Brilliant plugin! I love that most people won't have to fill in the captcha, and only suspicious comments are forced to do it. Works great!
I say "nearly perfect" only because nothing is perfect.
I run a pretty busy blog site -- with an average of 6,000 or so visitors a day. Akismet was excellent for flagging spam and learned to be nearly 100% accurate. But Akismet only puts the comments in a spam bin which has to be emptied, and we were getting hundreds of spam comments a day by October 2012. I was desperate and tried a number of different plugins that were supposed to solve the problem -- some claiming to be the all-in-one solution that would ensure that we would never see spam again, because the plugin would delete them. One boasted that there were "zero false positives," but I tested it and found that perfectly good comments could get lost with that plugin. (The author got quite upset with me when I pointed this out.)
Then I installed Conditional Captcha and set it to auto-delete spam that did not pass its test. Eight months later, I am still very pleased. We get the occasional spam that is manually submitted. The human spammer will fill out the Captcha, and the comment will end up in our spam bin. But we don't get more than a dozen or so a month, as opposed to hundreds a day.
Probably the two best things about this solution are
1) our legitimate visitors never have to fill out a CAPTCHA. (I dislike filling out CAPTCHAS!! How about you?) Neither do they have to check a box saying they are not a spammer. ;)
2) we do not give control over to a plugin that could block legitimate comments. Any comments that could possibly be legit will land in our spam bin to be manually deleted.
If you have a spam problem, I highly recommend the combination of Akisment and Conditional Captcha.
