<p>If your Blog allows new subscribers to register via the registration option at the Login page, this plugin may be useful to you. It includes a reCaptcha block to the register form, so you get rid of spambots. To use it you have to sign up for (free) public and private keys at <a href="https://www.google.com/recaptcha/admin#createsite" target="_blank" rel="nofollow ugc">reCAPTCHA API Signup Page</a>. Version 3 added extra security by querying antispam databases for known ip and email of spammers, so you get rid of them even if they break the reCaptcha challenge by solving it as real persons.</p>

ThreatPoint UK

<p>This plugin validates email in realtime using live connections and aggregated data, by leveraging the ThreatPoint email verification API service. One use of this is to prevent spam bots inputting content into comments, easily and effectively</p>
<h3>External Service</h3>
<p>This plugin allows administrators include email validation using a real time verification service provided by the ThreatPoint email verification API.<br />
The Plugin uses existing is_email functionality and passes manually entered email addresses to the restAPI service at ThreatPoint.<br />
The response back from the ThreatPoint API provides information related to the email validity(valid email, valid domain, disposable, free, role, risk score). Automatically stop spam bots from entering comments onto your posts by verifying the email address first.</p>
<p>The plugin calls the rest API (requires an API KEY) at <a href="https://verify.threatpoint.co.uk/api/v1/resources/" rel="nofollow ugc">this ThreatPoint api endpoint</a><br />
The rest API is only passed the email address from the contact form via the is_email function.<br />
This external service is called whenever a form using is_email is used. By default the Contact Form 7 is supported. You can include any form field name (email address field) in the plugin to override the default.<br />
An API key is required to utilise the service, although the plugin will operate without one it will not be able to pass the email address or call any data from the API.<br />
Your email addresses will not be validated without a valid API key.</p>
<h3>Privacy Policy</h3>
<p>The privacy policy for the api services is viewable here <a href="https://threatpoint.co.uk/privacy-policy" rel="nofollow ugc">privacy policy</a><br />
This plugin only passes the email address information – no other PII is transferred. The email address is analysed across the aggregated data within the ThreatPoint email verification reputation service and a risk score with email properties (valid, free, role, disposable) to the plugin. Simple rules within the plugin dictate whether the email address is considered valid(set through the plugin settings). The email address is stored in the email address aggregated data and used as part of email address consortium for all customers. No other data such as originating website is stored. Only the email address  is held, with date, time and risk scores associated with the request.</p>
