When shortcut aliases are made, they always start with a slash to avoid ambiguity (exactly like this artist named sao), so it would be /sao -> sword_art_online.
I don't see why we'd need more shortcut aliases at all though. Just use autocomplete.

As for the artist, the series vastly outnumbers his/her posts. I believe that we can change that to sao_(pixiv).
_(pixiv) qualifiers should not be used. The artist should be sao_(rakugakioukoku), I moved it.
