@DMD Personally I'm not bothered if City supporters use 100 names, but it would be annoying if a wum had several different usernames, because this gives an unbalanced debate on issues were people disagree and only plays into the hands of the wum.
I know what you mean, but unless they're arguing different views under their other names I don't really see how one name or six names matter that much. I have my opinions and they tend to be changed by facts or persuasive argument, not weight of numbers.
