I use Libretube as my kids' YouTube app. It uses piped instances to stream the videos, and you can pick the instance that works best for you. I'm wondering if there are any Instances that can be used to totally block all NSFW searches, thumbnails, and videos. Do you know of any other apps, ways, or ideas to make YouTube safer for kids? Let me know in the comments!
I think it's best not to have kids find entertainment on the internet because they will get exposed to stuff you don't want them to see cause its basically impossible to quickly catch all horrible stuff especially the sneaky stuff without being very restrictive like a approval process.
