When does a spoiler stop being a spoiler?

When does a spoiler stop being a spoiler?

When there's been (10~25) episodes since the event? Which stuff still warrants a spoiler tag and which doesn't? When characters regularly refer to the spoiler event, does that stop being such a spoiler?

When do you justify deleting the spoiler tags?

.....

Been bugging my mind ever since I went on a slight spoiler deleting binge on the Zexal pages.

I'd say a spoiler ceases being a spoiler when you can't avoid the information when looking into the series while trying to decide whether or not to start watching/reading. For example, I don't consider a First-Episode Spoiler a spoiler.

It's important to note that 'when' is not the only factor that matters, but 'what' as well. Major twists only stop being spoilers when they become It Was His Sled, minor plot points stop being spoilers when everyone who's currently following the series has had a reasonable amount of time to catch up.

A spoiler stops being a spoiler when it becomes general knowledge.

Until then it is a spoiler.

After reading Handling Spoilers, I'd say for our specific interests—

Manga: Ordinary events can be unspoilered when the following volume is printed in English (for the English-written section of the website). Minor twists should wait three volumes, major twists should wait six, and "holy crap! This changes everything" and the ending should remain spoilered until it becomes It Was His Sled.

Anime: Ordinary events can be unspoilered after two episodes after them are released in English, minor twists should remain spoilered for at least a month, major twists until the next season starts (plus a month for the later parts) and the "holy crap" stuff stays spoilered indefinitely.

Bearing in mind that many people reading the trope page are not going to be familiar with the series I see no reason to unspoiler things that are supposed to be properly revealed. I probably wouldn't have a problem if they made no sense out of context though.

Discussion of the spoilers can take place on the series thread where spoilers will no doubt be tossed around like they're nothing. I'd probably use spoilers on the forum outside the series thread though.

Spoilers are an imperfect system (as are shows that rely too heavily on plot twists for suspense), but I think the important thing is to remember they're there so that unsuspecting people don't come across information that could ruin their enjoyment of the series. I guess a feature to remove spoilers for you only once you've watched a work would be nice.

For actually writing wiki articles, I don't think anything ever stops being a spoiler. But for discusions in threads, that's a different story.

For discussion threads, it's pretty much whatever the thread's users agree on. For the threads of presently airing shows, only the latest episode is spoiler, and only for long enough that the threads visitors can notice that it aired. For older works, everything is is spoiler on the first page, then people might start openly talking about everything, or only cover the biggest twists, or whatever.

It's also depending on the genre, for example a mystery story's discussion should alway be more careful about spoilers than a harem comedy.

This.
