This only resolves YES if it's known conclusivly that this occurred. A very indirect reason like "I saw this person on Manifold and we got to talking elsewhere" doesn't count, but "I did it to manipulate a market" does. In other words, the counterfactual "if a specific market had not been created, the sex would very likely not have occurred" must be true. (I reserve the right to modify this description slightly if I realize a problem with it.)
