<h4>History</h4>
<p>Blocking spammers via htaccess or other server settings would do the job, but that would require<br />
to keep all the files in sync. So I decided to write a centralized solution that enables<br />
innocent users to remove their IP from the blacklist via removal request. As a blacklist gets queried<br />
way too often, I added some local detection of spammers to reduce load at my side.<br />
By now many additional features have been added, making this plugin a full grown anti-spam solution.</p>


WP-BlackCheck

• When data is sent: once per day via WP-Cron (and when an admin triggers a manual update).<br />
• What data is sent: no form submissions and no user personal data are sent. The request is server-to-server (HTTP GET) and only standard headers (e.g., User-Agent) are included.<br />
• Storage: the downloaded JSON is stored locally within your WordPress site (e.g. under wp-content/uploads in a plugin-specific folder).</p>
