Protip: Always give someone the benefit of the doubt and assume they are trolling before you automatically come to the conclusion that they are blindingly stupid, especially when it's on the internet.
It assures that you won't like like an idiot yourself if it does turn out to be trolling, and if the person really is that dumb, the worst that will happen is that you'll appear to be condescending.
I see things like this happen far too often on here, with amount of fake fandom drama that goes on.
