I'm sorry that the "why" has been explained several times - most prominently in the 1st post of this thread - and you keep asking but why not?
Really, it boils down to this: because the admins here said no. That's it. That's all that really matters. They don't owe you, me or anyone else here any further explanation, they don't owe you, me or anyone else where further justification. If they decide to expand on it, awesome - but they could just as easily stand by because we said no and you don't get to keep saying but other places are doing it, why can't we?
HF isn't other places, HF doesn't control what other places do. HF has taken a stance on this matter. You can dislike it from here to Helsinki and back, but at the end of the post HF has said "this is what's going to be allowed, this is what's not going to be allowed" and you can either accept it or you can stand up in your chair, scream I'M GONNA PRESS MY LUCK! and find out how long it takes before you hit a Whammy.
