The text of the logon failure message suggests a permanent ban rather than a temporary one.

>And I am US based playing on US server.

Then you have a whole wealth of quotes and assertions - including these ones just from this morning - indicating that KeyClone and similar programs are absolutely fine.

For some reason, even though we're playing the same game, I always feel that the European GMs aren't as switched on to this sort of thing as the US guys are.

Good luck on this - you're on solid ground with the 3rd party / GCD crap the GM spouted, but you know the situation with the fake names and girlfriend's account.

Post the email when you can - that should give us a better idea as to the actual reason for the ban.
