Someone above asked about what are the negative consequences of someone playing a non-capsuleer politician on IGS.
This is a bit of a difficult matter to explain, but I think it is in the core of how to make massively multiplayer games work for players together, so I'd like to try and answer that.
When you make RP about something that is local to your character (my clan has this custom that we X; the town I grew up in used to have a mayor who thought Y, etc), you do not restrict other people's world or the way they RP, because they can actually interact with you by saying "Really? That's interesting. Where *I* grew up, I do not think *anyone* did X/Y", and you can go on to discuss that and invent more things without having to establish what is "true" in the universe in general.
But when a player invents something that is true in the world in general - a high-up in a political party that everyone of a particular faction knows, or invents a custom that all people of a particular tribe are supposed to know of, or tries to pose themselves as a CONCORD official, or any such thing - and another RPer wants the facts to be different, they can no longer improvise together. The one who did not start it can no longer claim that their interpretation of facts (Sebiestor customs, or Gallente political parties, or whatever) is equally valid, but they are left with 1) accepting to play a minority, 2) contradicting and questioning the first player's words IC, 3) ignoring the whole thing OOC, or 4) contesting it OOC.
So the negative consequence is that it limits the way others can play, without their consent. You try to establish truth about the world as what you think the world is like, and everyone is forced to either ignore your RP or to play it your way.
I am not saying you cannot do that. But myself, I strongly prefer it when player-invented stuff is such that it is completely believable that my character has never heard of it, so that I can decide which way I want to take it without creating "splinters" of the world, where in one splinter one thing is true (e.g. "it is the custom of all Sebiestor to X") and in another something else is true. This, because in the long run it allows me to interact smoothly with a lot of people.
