I've seen this come up a few times on this board - and pretty much everywhere else on the internet - so I'm curious. How long do you think something needs to exist before spoiler alerts are no longer required? I mean, I think we can all agree that we can talk about the ending of, say, Planet of the Apes at this point without having the put spoiler tags around it, but where is the line drawn? A year? Five? Ten?
What's the statute of limitations for spoilers?
