So I've been thinking for a long while now of creating a blog consisting of short stories based around various classes and specs in the Warcraft universe. I'm aware of a certain amount of leniency in Copyright Infringe regarding fan fiction, providing a profit is not made from that fiction.
However, what if the blog contained ads that brought in money, but the stories themselves (obviously) were free?
Would a company take issue with making profit through hosting ads/donations?
(It is worth noting, I only think of money as a mere curious afterthought. My passion for writing fiction is genuine and I'll be going ahead with the blog regardless)
