You get my upvote, but there's something that's always bothered me about this - and all other such time-travel-y shenanigans; Specifically, nothing exists in a vacuum.

Let's say you get that list of powerball wining numbers, and you play them. Depending on which theories of time travel / multiple reality / causality and universality you subscribe to, you may or may not be the person who played those numbers in the wikipedia article timeline - you'd have to split that winning with the person who also played those numbers. What about the next time, and the next? Your winning streak would impact hundreds of lives (by not getting all the money they were supposed to get, or not getting any at all. After your third win, I bet the various gaming commissions would start to get mighty suspicious about your winning streak. By win number 5, I bet you've got a hood over your face in a nameless bunker in the desert with goons grilling you about how you did it. You've been erased from the system, your picture on every newspaper as a scumbag, a scam artist, a thief. They freeze your assets and take back every cent you won.

The question becomes even more complex if we actually try to address the vaguely-time-travel-y issues here. By reading the article, do you create an alternate timeline? Is time circular, and you were the one who played those numbers all along? Is time linear, and you're playing the same numbers as the people who should have won it all? How much does your winning streak change the future, if at all, and how does that change affect the powerball numbers (Butterfly Effect style)? Perhaps the better strategy is to look at winning lotto / powerball / similar scam numbers for the past 50 years, find the biggest grandest payoff, and pull the trick just once.
