Copyright

The copyright: namespace, while used on danbooru and e621, is not recognized on PTR. Use series: instead. Yes, even if it's a franchise like Pokémon or Fate.

If you see a copyright: tag in the wild, it is your legal and God-given duty to sibling it to series:, copyright: must be eliminated, and you are to aid in the cause. Destroy them all. Rip and tear, until it is done.
