Re: The miiverse admins...
I'm wondering when the spoiler obsessed culture phenomena is going to end. If you don't know that Vader is Luke's father, Keven Spacey was Kaiser Sose, Shiek is Zelda, or everybody is dead by the end of Lost should I really have to be tight lipped about it. Also since when are the most minute details of something considered a spoiler. If you're that worried about it I have some simple advice. Go live under a rock and stay off the internet.
I feel like with Game of Thrones is where this was really born. Fans of series love spoiling the show for non-readers - especially on the internet. It doesn't even have to be on show, spoilers can be posted as reviews on merchandise or even a game.
I think some things are spoilers sure, but if the content is say 10 years AND not tied to something happening today (meaning a remake-not a re-release of the same original content) - it is no longer a spoiler. If you watch the latest show in Game of Thrones and spill out the details of the episode days after - those are spoilers. If you play Super Mario 1, and post about the warp zone entrance - that is not a spoiler. If you post a secret exit to New Super Mario Brothers U - that would be a spoiler - probably until the Wii U's successor is out.
