How can I hide inappropriate content on YouTube?

Try using a bit of parental discretion. You can also clear your YouTube search history and watch history, which can help change what videos are suggested to you. It’s a good way to train the algorithm to know what you prefer.

Unfortunately, there's really no way to completely block all the content that some might find offensive. It's pretty subjective; what bothers one person might not bother another. Plus, even if YouTube set strict definitions, detecting what counts as vulgar can be really challenging for the algorithms they use.

A few things can help: 1. Clear your search history. 2. Delete past watched videos. 3. Mark videos you're not interested in as such, and do that consistently for a week. This should help in customizing your feed. Alternatively, you could look into using YouTube Revanced to add keywords to ignore.

You might want to consider setting up a YouTube Kids account if you're trying to filter out inappropriate videos. It's specifically designed for younger audiences and has stricter content filters.
