Aliasing zebrapie → zwijgen
Link to alias

Reason:

Artist changed name (or at least FA username). http://www.furaffinity.net/user/zebrapie/ says "zwijgen ☆ Moved ☆ ...", "ive moved over to zwijgen", and "Digital Artist".

( http://www.furaffinity.net/user/zwijgen links to other sites the artist is at .. and username at those site is zwijgen or variation thereof)

By the way, e621 username zebrapie changed tag of post #889174
from artist tag zebrapie to artist tag zwijgen
