Make Full Name accessible in admin view when "enable names" is off

i am describing the same problem here with some possible implementations

for me as a business owner i have to know who is who, but some people even in a closed community, they do not like to show their names, so that leaves me only one option, when a new user sign up i have to send them a message and ask them if for some reason they do not want their names to show in public to let me know to remove it for them but this is not a solution at all…
