If it's not there, one may also try checking the about page or the instance's Meta/Announcements/Status/etc. magazine(s), as it ultimately depends on where and if the admin has decided to make the info available so far as I can tell after glancing over a few Kbinstances.
As an example: kbin.cafe doesn't have the admin info/profile on the about or contact page, but they're the owner of the CafeMeta magazine.
