Mutant why question the decision to not list you when they gave a reason?
It was good that you got a reply and you know now why to either not submit to Mr Yum with sub domains or make the changes he requires and submit again... If he had said "Sorry your submission was declined" with no reason given you would have been |confused|
I like rules about as much as the next person and probably about as much as the people who write them but rules are for one reason only, to keep a level playing field. Link lists owners need our submssions, we need their traffic, my worse fear is rejection without a reason, if I am given a reason it's cool, I have two choices, I can 'think' fuck you I am not doing that don't bother listing me then or I make the changes and say there you go is that good enough...
