### Region

ALL

### Example URLs

https://nsfwyoutube.com/watch?v=BaW_jenozKc


### Provide a description that is worded well enough to be understood

I think it would be a good idea to add NSFW Youtube as a valid URL source and I've already made a pull request with this feature  implemented so that copying pasting similar links is sufficient, I think this should be added to the current YouTube extractor as another optional URL extractor type.  See:  https://github.com/yt-dlp/yt-dlp/pull/7857

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [ ] If using API, add `'verbose': True` to `YoutubeDL` params instead
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
