Great spam filtering for the price! For the price, Cleantalk really is the best option. I've tried many other services (free, paid, captcha on forms, etc.) and Cleantalk provides the best service with the least friction for my website users. Captcha services are often frustrating to me, so I imagine end users also don't like them... this is a great solution. I just upgraded to pay for 3 years at once for a discount, which makes it even better. I haven't needed or used their other services really as I have integrated options with my hosting platform, so this is just about the anti-spam software, but 5 stars for that!

As a web hosting company we had a few… As a web hosting company we had a few clients having issues with Woo Order Spam. This was by far the only plugin/service that actually stopped it. We even have gravityforms with no recaptcha running and this thing blocks it.

Great Support The service does what it claims to... That is already cutting down spam registration on my sites and email spoofing. But my reason for a 5-star rating is customer support. My sites are hand coded, and for some reason, either the site setup or my poor coding, the plugins failed to work at first. After an intensive investigation, the guys at Cleantalk tweaked the plugins to fix the issue with my sites. Almost all my support requests were answered within an hour. Customer service is above and beyond.

CleanTalk has kept my large websites… CleanTalk has kept my large websites with an international audience free from spam for several years, without me having to use reCaptcha or similar. Extremely easy to use. I installed a plugin, and voilà, the problem was gone.

CleanTalk Anti spam is amazing security plugin. CleanTalk Anti spam is amazing and would not feel comfortable about the security of my website without it. It stops spam comments and CleanTalk stops brute force attacks on my site. I would recommend it to any bloggers or website owners who don’t want their website attacked.
