Ok there's this PGA internet contest I've heard of, and basically long story short each person is only supposed to make one account, and if you make more than one you get disqualified. Obviously I know they can find out if you make more than one account based on your IP, if you were dumb enough to do it on your own computer. But what if you went to a internet cafe or something? Or even a school? Is there anyway they could connect the two accounts as being the same person? I know you can also use a proxy server, but I've heard there are ways to find out the real IP from them.
