I think they did it just because Justin has a 'bigger name' which is of course a [SIZE=-1]ridiculous decision and should be corrected.[/SIZE]
Justin is on the IRC channel every day meaning he's pretty active so I'd rethink what you're trying to imply. He has a "bigger name" because he talks with the "regulars" in real time so he is more "known".
Really, anyone in this tournament should go download mIRC and come to the official Smogon chat room as it will not only show/prove to Sonuis, the guy running this, that you're active but it also makes arranging battles 10x easier.
irc.dejatoons.net then join #smogon
That's all I have to say.
