Restricted Mode is an optional YouTube setting that, when enabled, limits the availability of potentially mature or offensive content.
For some users, however, this useful feature works in unexpected ways – it simply cannot be turned off. This has led to several complaints on official YouTube forums.
Users who encounter this problem say they can’t comment on videos or can’t watch certain videos at all. Instead, they are greeted with a message that the video is banned. However, don’t worry, as we have this problem under control.
