While it is easy to tell what entries deserve the deadpool, hidden is more tricky.
Sometimes I am tempted to put an entry into hidden, but I can't find a legit reason. I know that hidden entries should fall under this category:
Hidden: Entries should only be marked “hidden” if they are a duplicate or contain spam, gore, or porn. Anything else should be deadpooled.
Then, should those entries that are for one single derivative be hidden? Like this or this?
