I don't like to sound like sour grapes, since I received one of the teams that was URL editted. I'll play it, and I'll do the best I can with it.
But to me, it's a hack of the site. You make assumptions based on the way the site physically works, and you don't specifically make rules about people hacking the site.
I certainly know how to do this. I didn't do it because I consider it a hack.
And that's the bottom line... You're not using the draft center, you're essentially hacking the site. I know more about web user interfaces than most of the people on this site, and I could do 2-3 other hacks that are signficantly worse, but I consider that cheating
So in my opinion it's:
1) - Commish should have prevented this method
2) - It's still a hack, if the team can't be recreated in the draft center it's invalid.
I understand other viewpoints. I'm expressing mine.
