Ask HN: Why do so many YouTube videos have exactly 54 upvotes?

It may be related to the famous 301 view count where YouTube would stop updating the total pending further verification that the views are legitimate. See: https://youtu.be/oIkhgagvrjI This behavior was later removed in 2015, but I wouldn’t be surprised if something similar is happening here.

The app has been glitched recently and only shows the thumbs up count from the first video you've watched.

Maybe Hallucinations-as-a-Service?

Lot of people reporting similar months ago:

Sounds like a caching bug in the app.

Maybe system updates counts when it reaches that number?

Cuz it adds up to 9
