Personally, I've found that people pulling accusations of AI out of their ass to be even more annoying than the possibility that something might be AI.

Just like the people who thought they were helping by calling things fake long ago became more annoying than the possibility that the thing might be fake.

And so often when they included reasoning, it was the weakest shit, often boiling down to mistaking rare for impossible.

Or with AI, I've seen people accuse something because the grammar is too good and other idiots accusing when the grammar is too bad.
