Well, I watched a TTATO with theromper on it, and I'll accept that he has some teams and, at least in name, his daughter has others on which he has input. Honestly, this still appears to violate the spirit of the rules. At best, it was an unwise choice to play in the same worlds. As someone pointed out above, there are plenty of worlds through which to avoid the appearance of impropriety. You have ten teams between you, so you could keep that number of teams without having more than one in any world.
Congrats to theromper and emmaw1111 on their championship.
