The Admin sandbox has now been refreshed with 15.7. This is a new install and all old data and accounts are gone, history, removed, deleted, unrecoverable, etc. :)
It will take me about a week to configure the sandbox and I will make an announcement that the environment is available when I have finished. At that time new accounts will be created.
