I was involved in the analysis of your & rby case on the altt forum. I believe that you received a detailed explanation from the moderator about the final conclusion that was reached there.
On that forum, moderators have additional insight into the account's access history, and there was no connection found between the two accounts. This was crucial for your KingsDen account to remain "intact" and without any markings. (For rby it is a completely different outcome)
You also probably received a verbal warning that the moderators there are not convinced of your 100% innocence, similar to the reasons nutildah mentions here. I will not go into a detailed explanation here either, in my opinion, the case is closed, unless some new information appears
