Black Lister is a free Chrome add-on developed by Seph Reed. It falls under the category of Browsers and the subcategory of Add-ons & Tools.

With Black Lister, you have the ability to black list websites that you dislike. Once a site is black listed, any links to it will be blurred out whenever you come across them while browsing. Additionally, you can choose to highlight websites that you like.

This add-on proves to be most effective for users who frequently conduct research. By having your preferred sites highlighted and the ones you have deemed unworthy of your time blurred, you no longer have to exert much effort in finding the information you are looking for. Black Lister aims to streamline your browsing experience and eliminate the hassle of navigating through unwanted links.
