Block Site is now on the safer manifest v3. Please report the compatibility bugs you are experiencing. You can export the current rules to a JSON file and send it to me to investigate.

This extension will block access to websites of your choosing. A master password controls all customization options, as well as access to any blocked site. It's also possible to redirect navigation from one specific website to another. 

1. Block unwanted domains. 
2. Prevent access to a range of websites using wildcard matching or regular expression matching.
3. Reverse mode allows access to only some hostnames and blocks access to all others. 
4. Custom redirection; you can redirect a single blocked hostname to a new destination. 
5. Display a custom message on blocked pages.
6. Time and date-based blocking. Only block access to the websites at specified times and dates. This feature can be configured per hostname. 
7. Protect data leakage. This extension prevents certain hostnames from gathering network activity from your computer since blocking occurs before any network request is emitted to the server.

Risk impact

Block Site requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this extension. Review carefully before installing. We recommend that you only install Block Site if you trust the publisher.

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Block Site is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this extension.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension, especially ones with higher risk impact and/or higher risk likelihood.

You can customise it to your will and it does its job well. It doesn't look that bad despite what others say.
