Lol! It humors me how you pointed that out to me :P . And to be honest AS I posted that, I did realize that you did in fact say optional, but I see all the nitty gritty details open to the public or the option to, being an issue for those that wouldn't want that or who dont have the best record. People can push for it with shouts like, "Shinryu [Do you need it?] WHM BLM BLU Profiles must be open."
The user may have the option to hide it, but the public also has the option to see it, or push someone to see it. And that can hinder a players experience.
