No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. The recent download trend is too spiky to read.

I have been using this plugin with Contact Form 7 and overall it works well. The setup is straightforward, and it helps reduce spam submissions without making the form too complicated for visitors. It integrates nicely with Contact Form 7 and does what it is supposed to do. For a free plugin, it is a very useful solution. I am giving 4 stars because there is still some room for improvement, for example in terms of documentation or additional configuration options. But overall, it is a solid and helpful plugin.

Blocks login even if login protection is not checked in dashboard. Moreover, the right answer does not allow to login. You get locked out your own WP site.

As webmaster, I always use this great plugin in all my websites to protect any contact form (using CF7) and also the WordPress administration login page. Now, my websites are safer, and my customers are not bothered any more. Finally, the support is excellent.
