True, but I think it would help if it wasn't encouraged. If we keep our doubles in their own role plays and chat topics, having a double outside of them would be less normal to the community.
There's nothing we can do to prevent people's personal decisions, the most we can do is influence them for the better.
I understand why you don't like this idea, though. No one likes restriction of freedom, or feeling restricted. It's something all of us fight, including me. . . heh, I fight it more then I'd like to admit.
However, if this is truly what we need, if this is better for everyone, if this will end double deception for the most part, isn't it worth it?
