If the wiki becomes inactive (and if it's new enough for the automated adoption system), you will lose your 'crat rights which allow you to modify user rights, but you will remain an administrator as long as the adopter decides to let you keep those rights.

However, if the wiki is old enough to have to be adopted through the Adoption page here, you will remain your 'crat rights which means you can edit other user rights, but you cannot remove their 'crat rights. You will be unable to decrat them unless he does it to himself or you can convince staff to do so, which will not happen unless the rest of the community agrees to it.
