I hate to say it but this is one of those situations where I can see both sides. On one hand I was on a certain game system that allowed Player built cities. We had a group of griefers come in join the city, which was a RP city, and run for mayor, and the moment they were elected thanks to their friends, Deleted the city hall, and place up buildings with names like HaHa Rper's are Teh suxxors and Etc.
As for the argument, the Base belongs to the founder, we had Prior to the voting, a person who set up a city, and then Leave the game, which promptly died because we had no way for a long time to do anything with it or the group we were in because he had all the power. so either way, there are problems.
As for the founder starting a SG, it is his, and his alone. to a point that may be right. Once he opens the SG for others to play in, then he relinquishes exclusive rights to it particularly if he leaves. I see it as basically Superduper boy incvites me to his SG of justice Seekers. He had the idea and concept. He sold me on the idea and persuaded me to join. Now it is no longer. his SG but Our SG. He has final word but it is ours. We build it and make the fun together. Say he leaves, now Leader is up for grabs. say I get it. now it is my job to see that the ideas and Values superduper man had planned continue on as that is what we based this on. As for having people in the SG you do not trust, why do you have them? if you feel you cannot work or trust them, Tell them they have to go, be polite but say it is not going to work out, sorry.
anyways thats my 2 influences to this discussion.
