crawled sites as any other crawler could potentially
be guilty of this and I wouldn't want our scope to
creep to all crawlers.

+> Studies have shown that the training of just one LLM can consume as much energy as five cars do across their lifetimes. The water footprint of AI is also substantial; for example, recent work has highlighted that water consumption associated with AI models involves data centers using millions of gallons of water per day for cooling. Additionally, the energy consumption and carbon emissions of AI are projected to grow quickly in the coming years [...].
