Piggy Blocker is a Chrome extension developed by Rostyslav Onikiienko. It is a free add-on that falls under the category of Browsers and the subcategory of Add-ons & Tools. This extension is specifically designed for Ukrainians who are tired of seeing content in the Russian language on their YouTube.

Even if your Google account language is set to Ukrainian or English and your operating system language is not Russian, YouTube may still show you videos in Russian based on your location. Piggy Blocker helps you tackle this issue by hiding or blurring all videos with titles or channel names in the Russian language. Additionally, it can click "Not interested" on such videos, reducing the chances of them being recommended to you in the future.

Piggy Blocker provides different ways to block Russian videos, including just blurring them (with adjustable intensity), clicking "Not interested" and blurring, or clicking "Not recommend this channel". The extension works on the home page and sidebar recommendations while watching videos. It also offers local stats about analyzed videos and comes with both dark and light themes.

Overall, Piggy Blocker is a useful tool for Ukrainian YouTube users who want to avoid Russian content. It helps to keep your YouTube experience clean and tailored to your preferences. If you encounter any issues, the developer welcomes reviews and feedback. The extension is open source, allowing users to view the code or contribute to its development on GitHub.
