In Alliance,

If you do not want there to be players, that play UnTagged,
require everyone that plays on that server to be tagged!

(make it a true clan server)

this has been discussed a few times, and there are reasons a player would want to stay anonymized-- like restarting, for instance

we'd likely run into every restart making their own tag, which would just clutter things and not solve the underlying problem.

I personally don't have a problem with people playing untagged if they want to, but we want to ensure that all new players are at least well warned that this is a clan server and playing without a clan as a new player to this server is generally gonna be a bad, bad idea :p

if ur someone like me and theres just one clan that wants u then ull be happy ur not forced to be in a clan.
