Super plugin for Gravity Forms/Contact Forms 7 with excellent support and great communication! Highly recommend it to anyone. Thank you for your hard work!
Get the premium version, it is 100% worth it. Support is instant and helpful. The plugin has saved me a ton of time trying to parse spam and I love having the blocked data so I can make sure nothing got filtered that shouldn’t have. I currently use it with Gravity Forms and it works like a charm.
After using the free version, I decided to purchase the Pro for the extra features (invitation list). The support offered is great and the plugin is very powerful and easy to use.
I was really surprised by the personal, swift and helpful support. It gives me confidence that my website will work properly as I intended.
Thanks!
Thanks for this free plugin, for the ability to mark an entry as spam by creating blacklists. 50 black lists with 100 items per each is quite generous and typically enough.
All other functionality is PRO paid version, but still was helpful for my needs, as had a sicko lowlife client thief trying to get hundreds of dollars worth of our goods for free. PayPal closed his fake cheat claim and chargebacks and he attacked again and again and began pounding with dirty filthy emails that passed honeypot and other spam email plugins.
Thanks to yours I could create a list with his 8 frequently used filth and block him from submitting.
Thank you!
