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.

Best anti-spam plugin I've tested. Best anti-spam plugin I've tested. Great spam filtering for the price! I almost never need to access the dashboard, it does everything by itself. I would definitely recommend it to anyone. Cleantalk really is the best option.

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.

Best Anti-Spam and Security Plugin BY FAR Extremely affordable prices, especially if buying for a couple years forward. Due to its large database of dangerous IPs, Security works seamlessly, I bearly ever need to enter the dashboard as it just sends out emails with reports weekly, needless to mention that all denials that happen happen on their own without me needing to do anything whatsoever. Spam user registration as well as spam commenting is protected by Anti-Spam, and it works great! No complaints, at all. Would defenitely recommend to anyone out there, even for those with small websites, like me myself. alpinick.com

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!
