Being the original founder does not mean much, the assumption here is that if you haven't edited for a long period of time (adoption guidelines say 60-90 days), you have lost interest in the wiki. The adoption process states that the adopting user has to edit for at least 7 days in order to adopt a wiki, and there is a (small) chance that this will be reverted based on the fact that they haven't edited anything on the wiki after it, if you mention this to the staff member who approved the adoption. However, "I'm the original founder" is in itself not a valid reason to get bureaucrat or admin rights back, you were gone for over a year and have lost that right. It does seem like you already contacted an unrelated staff member.
