And I could go on, but it's not my responsibility to educate you. (Try expanding your search to 'Newbies' and there have been plenty of mentions of subdomains being declined within the individual link lists' rejection threads.)
Do you intend on creating a new thread for every free site which gets declined, and then argue with those who are trying to help you, or do you intend on learning from your mistakes? Again, it's your duty to learn about the business - it's not ours to teach you. I don't want to sound callous, but there are tons of new people constantly entering this business. We don't have time to spoon feed each individual.
