Well if you were going to poke under the covers and do it via manufacturing the protocol you wouldn't need much in terms of resources in order to accomplish it... though I think that's a bit more technical than a handful of users out of ~10000 would do, I would suspect you'd need far more people playing for that to become an issue. I was thinking of it more from a userland automation point of view, people using things to simulate human interaction like autohotkey, selenium, and such.
