What is WPD?

Why do you want to be where you aren't wanted? I am banned almost everywhere, and I have no problem with that. Most of humanity is scum, so I really don't need to deal with them. Let them have their echo chambers. But leave the few reasonable people to organize reasonable subs/forms. If this is allowed here, I would organize a sub for nonmorons, as I did on reddit, where all views are allowed but obvious morons are banned to protect the quality of the sub. So anyway, what exactly is the problem with allowing mods to mod their own subs?
