For 1, there isn't really any point in spoilers for anything. If it's real, it ruins the entire experience of the surprise of what happens next. If not you end up looking like an idiot say what would happen next and you're wrong. Now who would want that? (Really, it's embarrassing).

Now, back on naruto, I love the show, but I looked on the internet for the longest time looking for spoilers, and most of the time they were fake, and I ended up looking like an idiot (hence what I said earlier). When you do find one that's real the episode/movie seems more boring that exciting.

So see? Never use spoiler, unless of course you want to ruin it for you and your friends or embarrass yourself. Now remember, I'm not saying you can't use them, I'm just saying I don't recommend it. Thanks for reading.
