Simple to use. Keeps annoying and malicious pests away. I haven’t had any issues at all. I feel I have control over my website.
I like the fact that CleanTalk also has a killer anti-spam plugin so I have them working together without been concerned about any compatibility issues and website overloads.
I so much prefer it than having other security plugins that ask for crazy amounts every year.
Hopefully it will remain stable and trustworthy.
