I am a huge fan of the site. However, I often find myself seeing videos of categories that I blocked for that search. Often the videos I see have forgotten categories or simply didn't add them.
Now, I imagine more people encounter this. But currently there isn't a way to signal this.
Could it be a good idea to make that a feauture? It helps people find certain videos of categories they're looking for and helps others avoid categories that they aren't looking for.
