In some countries, the digital content that has legal problems will be restricted due to an issue. It applies to YouTube too. The same video will be available for watching in other countries. You can check in which countries the video is restricted.  With the help of a YouTube regional restriction checker, you can watch blocked YouTube videos in your country. I've posted a YouTube video on this as well as a blog post.

It will help users to watch blocked YouTube videos in their country. Once you have found if a video has been blocked in your country, using a proxy or VPN can help you to solve the issue easily.

Though YouTube has a strict moderation policy, some content may not be acceptable in countries where they do have strict laws. In order to abide by the law, YouTube has to restrict such videos. However, due to the advancement in technology, this is not an issue for a tech geek.
