HN really needs an AI filter. Most posts are AI company promotion now.
That is why many users here realized that there are protected accounts that can do that and everyone else cannot. Even in rare circumstances, the moderators sometimes unbeknownst to them, may also be indirectly allowing it.
It is far more complicated and one of the reasons why users here are fed up of the constant AI deluge on this orange site and nothing is changing other than there is more of it.
