Of course. I don't want to experience this while I'm on 100 volume with no airpods and suddenly I face a Yak containing weird stuff.

If you want to make it great, put these to options on setting:

1. Auto download, default: true

2. Auto play, default: false

Then they have full control over what to see / hear and how they use their bandwidth. You can enable this option per media type as well. For example download audios, but ask for videos and images ans GIFs.
