I don't think Google would agree that it's okay to ascribe articles written by different people to a single author. ^From way up above^ @aristotle Why not? It happens everday in the real world, writing and execution are not the same as authorship.
jimbeetle -- I don't see anything wrong with multiple authorship and multiple production efforts either. I also know that many authors use pen names, and many famous people use ghost writers. And I have no problem with that either.
But in this particular case the OP apparently intends to hide the fact of multiple aithorship, and in addition, intends to use spam techniques to create a fake reputation for this fake author. That's what I was referring to when I said "I dont think Google would agree."
