Nice Plugin for Combatting Spam (and typos)
Been using this a while and it works pretty well; very useful for rejecting fake email addresses used by spammers/scammers, and also for validating real users/customer email addresses (where they sometimes mis-type their email address).So, why only 4 stars? Well simply because I asked about personal (local) whitelisting and blacklisting functionality when I spoke to their onboarding rep., and was promised it would be added soon; over 7 months later, still no sign of this. As a paying customer, I would like the developers to be more responsive and deliver features/functionality that your rep. promised...

Works Great!
I have tried so many plugins, honeypot, captchas, IP blocking countries, user agents, etc. but this plugin is great! I was very skeptical at first but after several weeks of using this, we are now on a middle-tier paid plan. We use GravityForms so the plugin was VERY easy to configure and install. Super simple, bravo plugin devs!

Quick and to the point.
Exactly what I needed for my contact form 7. So simple to integrate with my contact form plugin.

Excellent in blocking SPAM
I have tested this plugin on several of my personal and business websites, it's awesome. No more spam and fake signups. Service pricing is also decent. Recommended.
