Our blacklist plugin will automatically verify user registration attempts, comments, or form submissions on your WordPress site against the blacklist function or specified records of blacklisted or whitelisted domains and put them in the logs for you to analyze.

It filters and categorizes users based on their domain, email, and IP, allowing you to effectively manage and control access to your WordPress site.


Filtering Multiple Domains

Our plugin provides you with real time assistance in managing blacklisted domains. It uses several online methods as well as local plugin lists to detect whether a domain is blacklisted or not.

This proactive approach ensures that hackers and spammers face significant challenges in registering and posing a threat to your website's security!

This is achieved using the following banned domains detector online services:

  1. SpamAssassin - Using a list of free email domains downloaded from SpamAssassin
  2. DNSBL - Using the DNSBL online service
  3. WhiteLists and Blacklists - All this service can be used together with your own blacklists and whitelists domains lists or with your own banned emails list.
