What Is the Standard Porn Blocker?

A standard porn blocker for Chrome works as a keyword-and-domain-based filter for your web browser.

The standard porn blocker has a pre-loaded database of explicit keywords. When you type in a website URL in the Chrome address bar, it checks if the URL you have types or any text that it can see from the website.

If it detects a keyword that matches the keyword on its blocklist, then it stops the website from loading.
