"If you are sharing your computer or internet connection with other persons that are also members of the Combine, you must register all accounts by sending the handles to register to email@example.com - this includes handles and the email addresses of all players using the computer. Players who are sharing a connection must all be members of the same faction or one or all may be freelancers."
The reason for same faction is because of using the same computer. The computer remembers your password a private message board. Or log-in to the combine site. Possible to read over shoulder of important faction email. Without this rule no one would allow registered multi-account players in their groups for the fear of spies.
Now lets say you are using a separate computer at all times. How do you prove this to the combine. Almost impossible, so not many people have the privilege to be in separate factions.
Can you prove that, Imazushi? Because if I were going to spy and pass information, the first thing I'd do is tell people I had separate computers/accounts/rooms/whatever.
Just join the same faction. Or ask REALLY nicely and see if you might be able to get in allied factions (one in the GE, and one in a faction owned by the GE, for example). They MIGHT possibly make that kind of exception, but I wouldn't hold my breath even on that.

You violated the multi rules, Imazushi. No one is saying the two of you are the same person, but both accounts logged on from the same IP and were not registered multis. You should contact firstname.lastname@example.org directly, or PM him on IRC (he is usually connected as 'Kyle'). I am closing this thread since discussion here will not achieve anything - you need to talk to him as he is the multi director.
