Investigating youtube shadowban

@dolphin Help me retroengineer youtube censorship

Sometime I cannot edit my comment. I get a 404 on the POST request. That's how I know.

Then if I switch account, my comment have disappeared.

Sometime if I comment somewhere else, it works.

Previous comments (unless really hardcore, which I get, against the rule) are still there and editable.

Yet all comment deletion must be motivated under article 17 of the EU digital service act.

Even more interesting. Here under a publication about an old woman who resisted the nazis.

If I comment a nice thing, comment goes through.

If I comment "test" under a comment that says "negationism", from the public page (incognito mode), i can see the comment having one subcomment. But when I click on it, it diseapear.

If i comment "test" under a comment from a ziobot account, same thing.
