Right, I think I’m understanding that: if a video from a year ago, and a video today, both had the phrase ‘review’ in the title, and that phrase was added as a dislike tag, it would hide both. However, because the ‘short video’ tag was implemented a few weeks ago, and can’t be added manually by the user, it currently only works for videos added to the feed since the ‘short video’ tag was implemented.
The confusion was that it’s difficult to tell from the intelligence tagging UI whether that tag has or hasn’t been applied to a video or not. The only difference between a tagged and untagged video is the ‘x11’ next to the short video tag in my screenshots. Maybe some ‘No tags’ text under the ‘Story Categories & Tags’ heading would do the job!
Idea-wise, allowing users to manually add the short video tag to a video on their end, or allowing users to add custom intelligence tags, would help with retroactive sorting for videos older than a few weeks.
