for most of the low hanging fruit it's as easy as copy-pasting the question into multiple LLMs and logging the output

do it again from a different IP or two.

there will be some pretty obvious patterns in responses. the smart kids will do minor prompt engineering "explain like you're Peter Griffin from Family Guy" or whatever, but even then there will be some core similarities.

or follow the example of someone here and post a question with hidden characters that will show up differently when copy-pasted.
