Of course it did, if you already knew the answer.

A lot of hints look too easy once you already know the answer, but you have to think about whether or not they'd be as simple for someone who has no idea where to start. And I think jojo's hint is at least a little challenging... not that it really matters, I guess, as the MP got solved quickly and by a few different people at once, so payout won't be all that high.
