none
used to block youtube videos biased on creator or title
left click block button blocks/unblocks by creator, right click does by title or by url
to block, it removes the video link, to block the current watched video sets the playbackRate to 0
can also hide watched videos
the videos on the sidebar of the watch page and on the video endscreen cant be blocked correctly as there is no creator id, only display name which is not unique, so all videos on the sidebar and endscreen will be blocked
