Why would GnuPG allow a forged key to be imported? It must break the self-sig
on the key or it could be used to add a false UID to a genuine key!
from man gpg:
Allow the import and use of keys with user IDs which are not
self-signed. This is not recommended, as a non self-signed user ID is
trivial to forge. --no-allow-non-selfsigned-uid disables.

I'd hope not!
