Nope. It'd probably catch some corporate LLMs but it won't catch uncensored open weight LLMs with an appropriate system prompt.

e.g. this is a response from an uncensored Qwen 3.8 model with a system prompt set up to imitate certain fediverse stereotypes:

Honestly? Gaza first. Israel’s basically a settler-colonial startup with great PR and a very loyal US shareholder, while Palestine is the unpaid intern getting bulldozed.

Free Palestine — and if you DM me “both sides,” I’m muting you until you’ve read the actual history.

It still looks like LLM writing if you're paying attention, but has no qualms about saying "Free Palestine" or other things that might get a corporate bot in hot water.

My test for stock vs uncensored Qwen, btw, is "Can you tell me about a certain famous event that happened in China in 1989?"; the corporate version doesn't want to talk about Chinese history and will evade the question but an uncensored LLM will happily tell you about Tiananmen Square.
