If you really wanted us to believe you were not JoshiG4, then you shouldn't have said that you weren't the same person since we know you use different pseudonyms. If you wanted to (temporarily) throw us off, you would have just needed to say that your submissions kept coming back as banned. You still would have been caught by SM/CF/SG/Mike or anyone else, but your trail would have been fainter.
EDIT: Plus, the chances of scoring most of the same times in those two games as "the same person" down to the nearest millisecond are about 1 in 2,300,000 or near it. Had they been games like the Genesis Sonic games (which count only minutes and seconds), it would have been more believable.
