Respectfully bring this up in a language the moderators understand in the appropriate forums, or in DM in Discord, or even in #leaderboards in the DKC Discord Server. No one here can help you. I'm going to assume they rejected the category idea because the point of RBO is to simply beat the bosses in reverse order. 101% RBO is just RBO with extra steps. Moderators however would be better able to explain the reason of rejecting the category idea. You've proven to be able to speak a decent enough English to be able to post in English, so I would recommend bringing it up to the moderators.

I just noticed you did post in the DKC forums (twice). It's not because you did not receive a response that they rejected the idea. Whining about it here does not help. Or I guess it did, because someone here is giving you advice right now (me) lol.

I used Google Translate, so I'm sorry if I misunderstood your message.
