And the List Keeps Rising

[Momiji]

There is an expiration date on spoilers. You wouldn't use spoiler tags when talking about how Aeris dies in FF7 or anything like that. Don't complain about spoilers for something three or so years old while on the internet discussing popular anime. Spoilers happen.

Isn't the rule here that anything less than 5 years old should be spoilertagged?

That's just what happens with popular things. Be careful of the Evangelion ones.
