Blacklist

A list of people or things that are (usually permanently) banned.

For example, users who repeatedly break the rules could be banned from posting to the website, and untrusted websites could be blacklisted by ad platforms.

Blacklisting is the ability of publishers to prevent certain advertisers from displaying ads on their specific websites.

Sites marked as spammers are blacklisted. If your organization or website is blacklisted, emails sent from your IP addresses will be rejected.

The blacklist is as scary as it sounds. If a company sends out a large amount of unsolicited email (spam), the IP address from which the company sends messages is blacklisted. If you are blacklisted, you will no longer be able to send regular emails. The Sin of Digital Marketing You Want to Avoid.
