User reviews
Pros
- Effectively blocks harmful and annoying websites, includingまとめブログ (summary blog) sites and low-credibility news sites.
- Convenient default lists of blocked sites that can be easily customized individually.
- Helps provide a cleaner, more comfortable internet browsing experience by eliminating spam, spoilers, and negative content.
- Valued by users as an essential tool especially for gamers to avoid unwanted spoilers and negative content.
- Simple and easy to use with options to add or remove sites as needed.
Cons
- The Firefox version's feature to hide censored Google search results stopped functioning, needing a fix.
- The extension can have occasional instability issues depending on the user's environment.
- Ads and content containing 'null' in the URL may cause misbehavior or malfunction in some cases.
- A suggested improvement is to automatically close filtered redirect pages for better user experience.

Extension safety
Risk impact
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, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
はちまバスター requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood
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.
はちまバスター is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this extension.
