Besides paranoia? No-Kin is a rather transparent fake.
Perhaps it's a moral lapse on my part, but I don't particularly care who's playing No-Kin. I'm actually quite amused at how seriously the accusation of double identities was taken and by how seriously it was pursued.
In an environment such as this, it is of prime importance that information is trustworthy. If this truly is a game, I've better things to do. If this is just a juvenile namecalling, and shouting match it would not matter who imitated whom, but since I don't consider this a game I do care that people be honest. I also believe that honest people try to adhere to the standards established for a venue namely----
Don't play games - Don't represent yourself as another person, create or use another screen name to avoid a revocation of posting privileges, misrepresent the site or your role in it, and don't misattribute a contribution you've made. (Parody exceptions would apply to the latter, of course, but it should be clear what you are doing.)
