said it a million times, that is a certified grade A reddit troll post. People always pose as experts on reddit. It's a very common way to troll the site and has been for years.
The truth is, without some dumb registration email like
viralmarketer@microsoft.com or other kinds of tracking admins can do, I imagine the good/real viral marketers will go undiscovered. The people with reddit accounts who eventually lash out like "fuck u im no viral i just like the xbone u fukcing idiot" are not viral marketers. People like this are a dime a dozen on /r/gaming. And when a popular game comes out, the whole damn /r/gaming subreddit gets taken over like the publisher bought everyone off but you. Not to mention trolling the classic way just by going against popular opinion. When people seem "passionate" about something like DRM, it brings out plenty of trolls.
It's very difficult to tell what's real and what isn't on reddit. A zero day account could mean troll, it could also mean someone protecting their identity. They could verify their story through a mod, but reddit mods fuck things up and cause scandals all the time. You don't even need an email address to start posting.
basically all the inferring about virals is no more than guessing. Are they there? Yes. Is everyone who talks positive about xbone a viral? No. Can you say for sure who is and who isn't? No.
