I know you are not looking to add new districts, so this proposal is intentionally not serious! Troy (or Babylon): sites that used to be actively updated but haven't received an update in over three years. Potemkin Village: sites that have a good-looking index page, but links to all other pages are broken. Germania: sites that started with megalomaniac plans but never materialized.
Hai - I personally don't really follow the Touhou music scene to let you know. I'm not really fond of it much at all. If you saw my album loot pictures with Touhou albums then that most likely means I am buying much older albums via artists I know.
