Fernando I thought you just had to ask ( when you're interested in fwa ), since I saw someone who had access.
This might be a misunderstanding from a badly-worded error message somewhere. Staff accounts on the site are only given to people who are already farm war league admins, in connection with the work they have to do as admins of that league. I think one of the older error messages says something like, if you should have access, ask your league head admin - this message is aimed at existing league admins who haven't yet onboarded to the system, not people who aren't part of any league administration.
If there is someone with an account on my system that isn't a league admin, I'd be very interested in details about this, because that should not happen.
Fernando I still haven't understood what you mean by "sensitive information"
When someone contacts Supercell support regarding recovering access to an account, to verify their identity, Supercell support idiotically asks them questions about their account's history that anyone with public records of the API can search for, such as previous names, clans, etc that their account used to have. This is why I made the archive private, because it was being used by people who lie to Supercell support to scam accounts and then sell them.
Additionally, some data is pre-emptively private to protect the privacy of individual admins, for example, the specific admin who removes a clan from a league cannot be seen by the public, but can be seen to those who are logged in.
