HN Blocklist is a free Chrome extension developed by Morgante Pell. It falls under the category of Browsers with the subcategory of Add-ons & Tools. This extension allows users to block other users on Hacker News, a popular online community.

Hacker News is known for its vibrant and engaging discussions, but sometimes certain users can consistently bother or annoy you. With HN Blocklist, you can avoid lengthy arguments and unwanted interactions by blocking these users.

Once installed, the extension adds a "block" button within comment threads on Hacker News. By clicking this button, you can easily block a user, and all of their comments will be hidden from your view across the entire site. You can also choose to unblock users at any time.

It's important to note that the blocklist is personal to each user and is not shared with others. Additionally, blocking only applies to comments and not submissions on Hacker News.
