If someone reserved the username admin/ssladmin/similar, would you honour it? I need to know for a project. Do not ask what the project is.
I would honour every username that isn't:
1) Already taken
2) In violation of a law within the EU on the basis of race hate, discrimination, etc
3) In the RFC list for common email addresses ( http://www.ietf.org/rfc/rfc2142.txt - postmaster, webmaster are in this list)
4) Used for domain verification purposes by common service suppliers (admin, administrator and ssladmin would be in this list - relates to email)
The last two are security related given that some variant of a username may be used in future email based tools.
An example may be the ability to send a PM directly from email and without knowing the other persons' email address. An address along the lines of velocio+siteHMAC@microcosm.app where siteHMAC was some token generated for you, and paired with the From address identified your site user would prove it wasn't spam... and I'd create a PM on the server and would send an email to the other user.
That's me inventing how it might function, but as a result of functioning like that you could see that I couldn't have usernames follow email standards.
