I would like to be able to filter out any results from appearing in the Youtube app which contain specific keywords, so videos and their metadata (description, etc.) which contain these keywords are not shown. The keywords may appear in the video name, channel name, video description, etc. basically in all the content youtube shows as part of the video.

A user may search for a filtered out keyword, and this search is not blocked, but in the result set videos and their metadata which contain the keyword are filtered out. For the user the result set looks empty.
