Works as promised! It catched 100% of the spam messages. False positive: 1x.

Ease of use

Easy to install, there are no complicated settings.

Value for money

It worth every cent!

I've used Joomla for years with a variety of captchas and honeypots. Always there was spam of some level that got through. Most of the time, I had to restrict comments significantly. Then I found this extension. Have seen only a couple get past it, and each time I can easily flag them and improve the service. Just wonderful. THANKS!

I have been writing on passive spam protection for a long time now & this is among the best i have found. If you have forms on your site and you want to have freedom from spam and the least amount of false positives, go for this !

Ultimate Spam Killer

Posted on 08 September 2014

I use JComments 3.0 with this plugin and spam is virtually gone. Since I don't have time to moderate each and every post, I rely on the kcaptcha for guests. I'm here to say that there are real people sending spam to your blog and bypassing the kcaptcha. Before Clean Talk, I got 25 spams a day. Now maybe one squeaks through every 3 months. I get a monthly report on how many were caught, and the developers are open to new suggestions. The tiny amount you pay per year is worth the headache of having to manually catch every spam that people are sending. Forget spambots, now we have to deal with human beings whose full time job is to send spam to as many blogs/websites as they can. Clean Talk gets them all. Extraordinary piece of software!

Works perfectly

Awesome extension. It works like a charm. Easy to install and configure. After one week of trial operation with JComments, the success rate is 100%. It's definitely worth to pay small subscription for this plugin.

Invaluable Tool

Posted on 12 August 2014

We use this extension to filter spam sign-ups on our staff login area of our company website. Works great, and for the minimal cost, it is well worth the investment!

I had a discussion forum with Kunena and was beginning to get hit with several spam bots a day and increasing. I got this little extension, and no more. Really. I was skeptical, but NO MORE SPAM was getting through.

I have had maybe 5 folks in 3 months who were stopped that I had to manually OK, but the service is amazing.

The trial is free and after 2 weeks you will gladly send in the $8/year cost!

Well worth it.

I'm using Cleantalk now on several commercial sites and it has significantly cut the number of spam registrations. Simple to install and set up. Great work!
