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.

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!

Description says: Supports block IP address by country or only allow IP addresses in a country. Upon install, plugin says: This feature only available Pro version So don’t advertise a paid feature that’s not in your fee plugin here, without such a disclaimer.

This plugin is an excellent easy tool to fight spam and scam website form messages. My clients were getting all types of messages trying to trick them into scams, and it wasted so much of our time dealing with it. Now we can stop them and it feels so good to have this stress and hassle gone. If you have a website contact form, this plugin is a requirement.
