I think that for the normal SGABB, the authors were kept anon from the artists during the prompt claiming so people won't just target the authors they know, but take a chance on something that looks interesting and written by someone they possibly don't know?

But yeah, art styles are sometimes very obvious (only if you know the artist, though. ;) )

Oh! Another question. Is this challenge called:
1) SGA reverse bang,
2) SGA reverse big bang, or
3) SGA reverse mini bang?
