Admin user editing standard user preferences

Is there any way to (as an admin) edit a user’s preferences? I’ve attempted to edit their subscription object directly within Mongo but every refresh of the object reverts the change. They have ‘every message’ email notification on, marked them as spam and now other users are getting their messages blocked due to the way the ‘social spam’ algorithms are functioning with GMail.

Currently I don’t believe there is a way.

If there is it might be possible via rest API.
