Very useful … as a general blocker. And only as that.

But zero protection against malicious actors.
Anyone can anonymously/pseudonymously report anyone as “AI” for censorship or competitive purposes, or request list removal (but possibly fail to get it even if not AI).
And the only decision factor is basically the gut feeling of a human with no noted education in psychology of manipulation, the scientific method (and scientific philosophy behind it) or formal logic.
(People always assume that because they are trustworthy to themselves, everyone should trust them. And that they are not prone to manipulation and know better. But in reality, those are in fact the easiest targets to manipulate.)
[Devs: I’ll change this if I can verify that it is wrong. But I’m a professional in that exact field, so I require something proper. Interpreting this as being personal, is not it. :]]

The add-on’s whole world will collapse and it will either fall under authoritarian rule or dissolve in the chaos of anarchy, as soon as it gets popular. But that is very likely true for all other similar add-ons, and in fact any crowd-sourced service ever. They all don’t manage even the first concepts of how to approach solving this.

But hey… A nice channel blocker! :)

I had to remove this since two imagine dragon and one stone temple pilots tracks on my like list were marked as AI. these are official releases 8 years old. Then at the same time there's still tons of ai generated videos from content mills making it into my feed. Also I don't care about creators using ai as a tool within reason, i just don't like content mills that use ai for everything.
