pyaokitty_(artist) / sailorsyaoran / syaokitty are the same artist.
http://www.furaffinity.net/user/syaokitty/
http://syaokitty.tumblr.com/
(and a few others)
Which tag should we change/alias the other two to?
Probably syaokitty, because that's the Furaffinity name and the main Tumblr blog.
In this case, we'd alias pyaokitty rather than pyaokitty_(artist)
