doltics

Doltics Radar checks enabled WordPress flows before they complete. Admins can enable protection for outbound email, submitted comments, and account registrations under Settings > Doltics Radar.
Email protection uses WordPress core mail hooks when available. Doltics Radar also includes a Mailgun compatibility adapter for Mailgun versions that replace <code>wp_mail()</code> without calling <code>pre_wp_mail</code>.
<h3>API Contract</h3>
The plugin sends a JSON <code>POST</code> request to the URL <code>https://radar.doltics.com/score</code> :
<pre><code>{
 "text": "The sample text",
 "locale": "en"
}
</code></pre>
The API should return JSON using one of these response shapes:
<pre><code>{
 "score": 0.95,
 "classification": "spam",
 "signals": {
 "token_count": 10,
 "unknown_word_ratio": 0.1,
 "spam_keyword_score": 0.61,
 "uppercase_ratio": 0.34,
 "exclamation_density": 0.3,
 "url_count": 1
 }
}
</code></pre>
Numeric scores are compared against the configured threshold.

This plugin disables default WP registration page by redirecting users who access the registration page URL to the default WP login page. If somehow you still want to accept user registration but want to disable default WP registration page to prevent bot, SPAM registration or something like that, this plugin is for you. No settings needed. Install, activate, done.
