Well if Cyranule didn't approve of you impersonating him you would be the one requested to change your name
(probably would receive a ban too for griefing him if he that upset about it or the actions you did while impersonating him)

I handled that case here
http://forum.meleegaming.com/na-%28official%29/ban-lilly_lefluer/msg818484/#msg818484

And here a word from Kalam when I asked around the Admin forums

I believe as long as the first person with the name is okay with it, it's alright.

The player in question should know the risk what his doppelganger could/would do with his name.

Edit:
Notice I didn't answer your last question I would recommend him to tell his "friend" to change name since we do know that he had that character name before his doppel did. If force is needed it there  always a option to post on the forums about the problem 

Problem in the lilly case is I noir do any of the other admin I believe; know who had the name lilly_lefluer first, they could always try adding numbers(aka apply a namechange to get those numbers) to their name to distinguish themselves. i.e Chinaserf (x,y,z...etc)

With the limitation of the game chat not being able to tell the difference between I and l  if the case of CyranuIe and Cyranule  both being in the server and an admin being present in the tking rampage would it be better to let the rampage continue or ban both so the other players can enjoy themselves.

Through you are quite right about waiting for the logs, but still I most likely follow my senior colleagues advice on how to handle strange/unique "events".

[Cyranule]

Ban both and later check logs to see who actually did it. 

For the record there is someone running around as CyranuIe_BRD. 
He doesn't seem to teamkill much but he's awfully bad whoever it is.

A little trigger happy, but overall doing a fine job.
