Downranking youtube promotes porn even in safe search

Hello!

I'm working on a goggle which downranks "too popular websites" with the aim that I'd see smaller creators more often.

It seems like the videos section in search results is mandatory, so if I heavily downrank youtube, which often populates the video results, the video results are still there but with not so exact matches, very often porn. This happens even on safe search moderate setting.

It seems hard to downrank porn with the current goggles syntax, since the domain and path often do not contain relevant keywords for successful downranking, instead the `intitle` option could be useful here. Relevant keyword downranks still do decrease the frequency, helping a bit.

If Brave has safe-search team etc. they could find this useful:
```
$site=youtube.com,discard
```

Alternatively I hope that I could disable/hide the video results completely, or to make them appear based on their assumed relevancy, currently the video results are always at the top.
