Send Denial – a spam sentinel
This plugin will enable honeypot and other anti-spam techniques (in future versions) to protect your business and mailbox from automated script spammers. In “basic” honeypot mode there will be zero impact on your users. they won’t see a captcha or puzzle to solve, they can just use your websites forms. Plug and play
This plugin will be compliant with GDPR guidelines as it won’t call external apis or databases at all. In future versions there might be a local database table (in your database) where failed submissions (from bots) will be stored so you will have total control over the data.

WP-Biz (Ryan)

The “honeypot” technique for SPAM protection is invisible to humans, and tricks robots into filling out an invisible form field. Then, if that invisible field has been filled, the form cannot be submitted. Easy, non-instrusive SPAM protection.
No settings to set, this honeypot is added to all Formidable forms on your site, unless the user is logged in. When SPAM is suspected, the form will not be submitted and the visitor will be alerted to this fact.
Tested to work with both Formidable (free) and <a href="http://www.wpbiz.co/go/forms" rel="nofollow ugc">Formidable Pro</a> (best bet for awesome form power!)
A note to Formidable Pro users: You paid to receive extra features in the Formidable plugin. Me too, it’s well worth it. This Honeypot plugin, and Ryan (the developer) are not connected to Formidable in any way. Since this adds another very helpful feature to Formidable, I ask you to send a <a href="http://wpbiz.co/donate/" rel="nofollow ugc">donation at WPbiz.co</a> to say thanks and encourage future developemnt.
